The best this you can do for your engine, is to ensure that air flows through with ease and doesn’t cause any unwanted stale air to cause problems, this is especially the case in diesels. Over time this stale air can cause buildup of dirty residue left behind by the burnt fuel and oils, which will shorten the life span of the engine as well as increasing the fuel economy. To prevent this from happening, you need clean air to be forced into the engine and then forced free of the car, this can be solved with a combination of accessories, most notably is a snorkel. By adding a high quality snorkel like a Safari Snorkel, will then force the clean cool air from the roofline of the vehicle, right in to the engine, which then gets pushed free of the vehicle via a larger diameter aftermarket exhaust. This flowing effect will then allow the engine to work less, therefore creating a better fuel economy and longer life span of your vehicle. This fuel economy saving and extra power can also be increased as well as managed with the help of a performance chip / module, like the Steinbauer module which talks to your engine to ensure that it is only producing power, when it is actually needed. By changing when your engine produces power, you will gain up to 25% more power and torque, as well as an added extra amount of fuel savings.
Owning and driving a high-performance vehicle is a pleasure. You can feel the intense G-forces pushing you back into your seat as you hit the gas, the smell of your tires burning, and the awe of bystanders all leads to a very satisfying experience. However, for some, this isn’t enough. The sound of the exhaust system must also be up to par with the vehicle to get their hearts pumping.
So, we have compiled some of the best exhaust systems that will take your vehicle to the next level. Whether you’re just using your vehicle for your daily commute or for the next trip into the outback and wilderness, we got you covered. Before you purchase an exhaust system for yourself, take a look at all the options. You should also learn how a high-performance exhaust can improve your vehicle’s power, sound, and efficiency.
The main considerations that people make when looking for a new exhaust system are efficiency, increased torque, and pulling power. Aside from that, here are other things that you should know about 4WD exhaust systems:
You can add a snorkel: Snorkels are designed to force stale air out of the engine and lets in the fresh air. If left unchecked, stale air can cause a build-up of oil and fuel residue that can result to fuel inefficiency. To be sure, get a snorkel that has a large diameter exhaust to help get more airflow to the engine. You car read more about How 4WD Snorkels Work here.
Noise does not equate to performance: Loud exhausts are useless and they can be bad for your vehicle. Exhaust systems that are of good quality tend to change the sound of your exhaust because of the larger diameter exhaust. When combined with the high flow muffler and catalytic converters, it can offer a better performance and fuel efficiency.
Size definitely matters: Exhaust systems with larger diameters would release unwanted turbo back pressure and improve the fuel efficiency of your vehicle’s engine. Aside from that, removing back pressure will also reduce turbo lag and exhaust gas temperature which is useful when towing vehicle up on steep inclines.
Do-it-yourself installation: Most third-party exhaust systems come with all the parts that you need to install them and use the factory mounts of the stock exhaust system. So, it will be relatively easy especially if you follow the instructions religiously or scour the internet for tips and tricks. If you feel that you’re not up to the task, you can always hire a professional to install them for you.
Options abound: There are tonnes of options that you can choose from, however, finding the one that fits your vehicle might be tricky. If you plan on sticking on the bitumen (get the full aluminized mild steel), drive on the coast (aluminized mild steel is ideal for this situation) or travel on off-road and beach track (full grade stainless steel should be at the top of your list), there are always a lot of options for different use cases.
