Types of Exhaust Mufflers

Chambered

Reliant on the method of deflection, chambered mufflers have multiple chambers inside them. When gases pass through them, the chambers reflect their sound waves, making them cancel out each other. The clever design of chambered aftermarket exhaust mufflers makes them a great middle-ground option, as they don’t affect performance as much as a stock muffler.

Straight-Through

If you want something that’s more free-flowing, a straight-through muffler is what you should look for. Why? Well, as its name suggests, it’s made so that exhaust gases pass in a straight line. This helps improve performance and reduce backpressure. While a straight-through muffler has packing material around the straight pipe that runs around it, it’s not as good at keeping noise down.

Resonator

When performance is not an issue for your car, but you want to improve how it sounds in the back, you should consider getting a resonator. This type of muffler is usually found alongside the two to reduce or eliminate sounds such as buzzes, hums, and high-pitched noises. Resonators do this without affecting performance whatsoever. However, because there’s no trade-off, they are quite expensive.

Dual-Exhaust

Upgrading your car’s muffler isn’t always the best choice when it comes to improving performance, as not all outcomes are the same. If you plan on making your vehicle better for towing, you should also upgrade your exhaust system, not just the mufflers. I say mufflers because, in this case, you’ll need two of them, as it’s a dual exhaust system that helps make towing feel more like a walk in the park.

Reverse Flow

Made in the shape of an “S”, a reverse flow muffler’s goal is to make exhaust gases take a different path than they would with a chambered or dual-exhaust muffler. Also known as crossflow mufflers, they make the gases go around bends and curves until they cancel each other out. This significantly reduces engine noise, but it also affects the power and speed of the engine the least out of the above-mentioned mufflers, except for straight-through mufflers.

Tripleflow

Often called a turbo flow muffler, a tripleflow muffler is probably the best at reducing noise coming out of an engine. Their design helps gases travel a greater distance to cancel each other, but that affects performance in a negative way. This is what also makes tripleflow mufflers the most restrictive option. They are also heavier than a chambered muffler, but still better than a stock muffler in both quietness and performance improvement.

Materials of Mufflers

Aluminised

Aluminised steel mufflers are the most affordable option, but also the lightest. While this means they’re easier to install and help with weight savings, they are not suitable in areas where salt and snow are present, as they can start to rust rather easily. Otherwise, they are a fitting option in warm climates.

Stainless Steel

If you live in an area where snow and road salt are present for a good part of the year, stainless steel mufflers are the way to go. They can withstand years of such abuse without any corrosion appearing, even on the surface. However, they are much heavier and pricier than aluminised steel mufflers.

Titanium

With a titanium muffler, you get an even lighter solution than an aluminised steel one, one that just doesn’t rust. Because of this ideal combination of properties, a titanium car exhaust muffler is also the most expensive of the three.

Benefits of an Aftermarket Muffler

Cost

The main reason why you’d want to go for an aftermarket muffler is its price, which is usually much lower than that of an OEM one. This alone makes it a worthwhile investment, as it can save you from a larger expense for something that will still last a long time.

Performance

With an aftermarket car exhaust muffler, you can definitely improve your vehicle’s acceleration and even MPG from what it comes with from the factory. This is especially the case with performance-oriented mufflers instead of ones meant as a replacement.

Fit

Despite being made by a third-party manufacturer, an aftermarket exhaust muffler fits exactly as an OEM part. This means you can find them at most online and brick-and-mortar shops with ease, as they are widely available, unless you have a rare car.

Options

There are plenty of solutions to choose from as far as design and build quality go. This means you can find a muffler for your desires and your pocket, albeit not in equal amounts.

To ensure your car battery works as it should and remains topped up and healthy for longer, consider investing in a reliable 12V battery monitor. This affordable and compact wireless device connects to the battery and keeps an eye on battery health. The data it collects is conveniently beamed to your phone in real time, so you know whether the battery is charging, discharging or nearing its replacement date.

Battery Monitor Basics

Batteries require maintenance and periodic charging to stay on top of their game. A 12v battery monitor provides relevant health metrics so you’ll know exactly how the battery is holding up and whether you need a functional replacement. The device registers the state of charge, the terminal voltage, how much current is flowing in and out of the battery, the consumed Ampere hours, and temperature.

Monitors inform whether the battery is charging with the engine on, whether it is discharging (for instance running power to the starter or high-current electrics like the AC), how much voltage is left before it reaches dangerously low levels, instances of surges and electrical faults (such as faulty alternators, chargers or frayed wiring) and if the battery is overheating or leaking. Metrics outside recommended levels are accompanied by alarms and visual alerts. The goal is to extend the battery lifespan, ensure your unit stays topped up and can supply power when it’s needed.

How Monitors Work

Most monitors are voltage-based, meaning they constantly measure voltage to calculate the state of charge and how much power is draining from the battery to charge essential vehicle systems. Devices are simple to install, attach to the battery terminals or a compatible port and with enabled Bluetooth or Wi-Fi, send readouts to your phone via an app. Drivers can set thresholds for various metrics, with alerts or notification warnings when levels are exceeded. Apps are also intuitive and easy to use, with simple layouts, and legible readouts that cover all the basics.

Why You Want One

Practical, functional and simple to use, Wi-Fi and Bluetooth battery monitors aid you and your car in more ways than one:

• Real-time monitoring – monitors register instant changes in current, voltage and temperature to give you a good understanding of charging rates, current and overall battery health, and whether there are underlying issues with other car parts, such as the alternator, starter, wiring, or electrics like the car driving lights.
• Alerts and notifications – take active measures to extend battery life with the help of alerts and notifications. Monitors warn of overly low voltage, risks of engine stalling or downgraded performance, overheating and sulphating batteries that can corrode vital vehicle systems, and possible safety issues.
• Timely replacements – most batteries have 3 to 5-year lifespans, depending on how and where you drive. Monitors inform of advanced wear, deteriorating battery health and the need for a new unit. This spares drivers from being stranded in the driveway, carpark or roadside.
• Savings – save money on unexpected replacement batteries, towing services, vehicle repairs (alternators fail soon after a dead battery) and the time lost in procuring a functional battery.
• Ease of use – monitors and apps have a berth of useful data, yet aren’t overwhelming. Simple interfaces and timely alerts across all smartphone platforms are easy to use and understand even for newbies.

Features to Look For

While all monitors provide basic voltage and current data, added features and functionality mean money well spent. Additional features to look for include:

1. Crank testing – the cranking mode test determines whether the battery has enough power to turn over the crank and start the engine.
2. Charge testing – monitors inform of the charging voltage at idle and at higher RPMs. This ensures drivers that the charging system is in working order.
3. Historical data – be informed about voltage levels, charging, and discharge rates, battery temperature, and multiple metrics over chosen periods. Drivers are aware of changing patterns and can take suitable measures to prolong battery life.
4. Safety features – choose a 12 Volt battery monitor with short-circuit protection and the ability to protect vehicle systems during electrical surges.
5. Monitoring multiple batteries at once – utes, campervans and other vehicles rely on deep-cycle batteries for additional power. Go with a monitor that can monitor voltage and charge rates in multiple batteries in a single go.
6. Compatibility – ensure lead-acid, AGM or lithium batteries get the charge they need and can supply your car, caravan or campervan with power and a monitor calibrated for your battery type.
7. Bluetooth range – newer Bluetooth formats allow monitors to be used at greater distances. This means no issues when monitoring batteries in towed vehicles, or observing battery condition in parked vehicles.

If we take time out of our busy schedules to do something we like, something that truly brings us joy and satisfaction, we can greatly improve our mental health and overall well-being. In fact, there are multiple benefits of having the right hobby, which can only enhance our quality of life and bring more balance and happiness into our daily routines. One such activity that has gained immense popularity in recent years is collecting lifelike and incredibly detailed RC nitro car models.

How Do Nitro RC Cars Work?

So what exactly can you expect from nitro models as opposed to other types of RC cars? Nitro-powered varieties are radio-controlled vehicles that run on a special blend of nitromethane, methanol and oil. These miniature versions of real-life vehicles can reach impressive speeds and offer a more realistic driving experience than their electric counterparts.

Instead of relying on batteries, which can require frequent recharging, nitro RC cars use small, lightweight two-stroke engines that are powered by the nitro fuel mixture. While they do require some maintenance and care, nitro models offer a unique experience for hobbyists who enjoy tinkering with engines and appreciate the sound and smell of a real car driving by. Sure, you’re getting a smaller version, but the intricate details and realistic performance make it all worth it.

Types of Nitro RC Cars

While there is certainly a lot of variety in terms of RC nitro car models – including trucks, race cars, and even monster trucks – they all rely on one of three starting methods. Even if the final product is similar, the way you jumpstart your RC car can greatly impact your experience and enjoyment of the hobby.

Pull Start

If you’ve ever used a lawnmower with a pull cord, you’ll be familiar with the way a pull-start nitro RC car functions. A simple tug on the cord engages the engine and gets it running. This is a fairly effective and easy method for starting the engine, but it’s not exactly the most durable option since the cord can wear out or break over time.

Another downside to pull-start engines is that if, for some reason, the engine doesn’t start, tugging at the cord repeatedly can get pretty tiresome and frustrating. Going at it again and again might get the engine going, but it can also leave you feeling exhausted and defeated.

Shaft Start

As opposed to relying on a cord to get the engine going, a shaft-start nitro RC car uses a handheld motorised starter to turn the engine over. This method is more reliable than pull-starting, and it also allows for a smoother and easier starting process.

However, this option does require an extra cost as you’ll need to purchase the motorised starter and battery separately. These two items can add up to a significant amount, despite the convenience that they provide.

Onboard Electric Start

The third and final starting method for nitro RC cars is the onboard electric start. This is a highly efficient and convenient option as it relies on a built-in starter motor to turn the engine over. Much like their real-life counterparts, these models use a gearbox and a starter motor to get the engine running.

This method is by far the most user-friendly and convenient option, but it does come at a higher cost. Not only will you need to purchase the starter equipment, but you’ll also need to ensure that your RC car has enough battery power to start the engine every time.

Storage and Maintenance Tips

As much as we all enjoy playing with our RC nitro cars deliver an exhilarating driving experience, it’s important to properly store and maintain them to ensure longevity and optimal performance. When you’re not using them, it’s best to store them in a cool and dry place, away from direct sunlight and moisture. This will help prevent rusting and other types of damage.

If you want to keep them in a display case or on a shelf, be sure to place them away from any heat sources, as this can also cause damage. If they’re exposed to extreme temperatures, it’s best to let them cool down or warm up before starting the engine and driving.

Additionally, properly cleaning your models after each use is crucial. This includes wiping down the exterior and removing any dirt or debris from the wheels, gears, and other moving parts. You should also regularly check and replace any worn-out or damaged parts to prevent further issues. You may also want to consider using a fuel additive to improve the engine’s performance and prevent corrosion.

For me, it’s the condition of the seats that I just didn’t bother too much with. And though I went with the better cloth and adjustable lumbar support; I was too stingy to get a decent set of seat covers. Now that the driver’s seat is one notch from being totally ripped and in need of replacement, I’ve decided to get some universal car seat covers. Better late than never.

Types of Car Seat Covers

Seats are one of the first things to consider when optioning a new car interior. Forget all the gizmos, think of seating comfort first and foremost. Different seat types and difference in materials varies greatly among trim levels. I often go with the middle ground – not too cheap, and not too expensive. My polyester seats have seen all the wear and tear that comes with daily driving, and being an SUV, some light off-roading with the added dirt.

For seat covers, you can either go for the same materials as your original seats or change to something completely different. Materials vary greatly – some are suited for daily driving and are able to withstand all the grinding of keys, phones, groceries and stained jeans. Others, like real or synthetic leather, will give your car an upmarket feel, yet may be prone to more damage over time. Maintaining seats of different materials will also be something to consider here.

Polyester Seat Covers

Polyester is the fabric most buyers choose in a new car. It is comfortable and durable enough without feeling cheap. The mesh is breathable and doesn’t feel hot in cars exposed to the sun for longer periods of time. It has a non-slip lining that doesn’t stick to your legs, great for long, hot Aussie summers. However, polyester absorbs liquid easily, so try not to spill your latté. Getting stains out might prove a challenge. All in all, decent polyester seat covers can go a long way in providing much-needed comfort while driving, with a few niggles.

Leather Seat Covers

Leather can give an entirely new feel and look to your car. Depending on the quality of the hide used and the level of stitching, prices can vary considerably. Leather, in general, is the most expensive material for car seats. However, it goes well with the leather on the steering wheel or shifter, and any accents inside. It is soft to the touch, doesn’t let liquids through, but needs regular cleaning. It can get hot, so it’s not the best choice in hot weather. Besides oozing luxury, leather seat covers will give an old-school feel, good if you’re restoring an old classic but don’t want to shell out for full leather seats.

Faux Leather Seat Covers

Faux leather, or leatherette, gives you the look of leather without the high price. It is made of a mixture of synthetic materials, mainly vinyl. Options on new cars will be pricier than typical polyester seats, but cheaper than real leather. The use of synthetics keeps prices down but also appeases the eco-conscious buyer. Faux leather covers can be slippery and hot, won’t provide the comfort of real leather or the breathability of polyester, and tend to develop cracks over time. On the upside, it is easy to maintain and clean.

Alcantara is a combination of polyester and polyurethane and mimics the look of suede. It is soft to the touch, has a non-slip surface, is generally breathable and resists fire and liquids well. The downside is that it wears quickly.

Nylon Seat Covers

The cheapest material for seats and seat covers is nylon. It is durable and doesn’t get hot in warm weather. It is not as comfortable as polyester or leather, gets stained easily, but its low price might be tempting.

Other Seat Cover Materials

Sheepskin provides the best comfort, stays cool in summer, and provides warmth in winter. It doesn’t stain, wicks off dirt and liquids, but is also quite expensive. Lower quality synthetic alternatives to sheepskins are acrylic seat covers, which are much cheaper and easier to wash. The most durable covers come in the form of canvas, though are rough to the skin and best suited for work vehicles.

Getting The Right Seat Covers

With all the options available, it might get confusing as to which seat covers to buy. Consider a few things – the current state of the upholstery on your seats and how you plan to use the seat covers. If your aim is to protect your worn-out seats, yet don’t mind a little discomfort, then get canvas seat covers. If you want an affordable everyday cover with reasonable durability, then go for nylon or polyester covers. They are the most available and easy to find. If you’re looking for a more luxurious feel, go for the synthetic or real leather options, but be prepared to part with more of your cash. Leather and Alcantara covers might be hard to find and may need restitching to fit your seats. Get the material you’ll be comfortable with for the long haul.

Finding seat covers for sports or custom seats may prove difficult, especially in less accessible materials. Universal covers, on the other hand, come in a one-size-fits-all configuration and are cheaper and readily available. And lastly consider how long until they’re replaced. Some seat covers, nylon, in particular, are machine-washable, which makes them good if you have pets or use your vehicle for work. Others, like leather, require spot cleaning with microfibre cloths, detergent and sprays. The aim here is to keep your car looking good and protect your original upholstery. A well-maintained interior will save you money in the long run, especially when it’s time to sell.
