Aftermarket Exhaust Systems: The Ideal Performance Upgrade For Your Isuzu

If you’re an Isuzu owner who wants to improve their vehicle’s sound, look, performance, fuel economy, or all of the above, then you’re probably looking to buy an aftermarket exhaust system. Aftermarket exhaust systems are the most efficient and affordable ways to give your Isuzu extra power, make it sound more aggressive, improve its mileage and give it a better look. In order to understand how they do that, you need to know how aftermarket Isuzu exhaust parts differ from the parts that your Isuzu came out of the factory with.

Exhaust Manifolds

The exhaust manifolds are the first point of contact for the exhaust gases that come out the cylinder head. Stock manifolds are generally heavy-cast, whereas aftermarket Isuzu exhaust models are tubular manifolds. The main reason aftermarket, tubular manifolds perform better than their exhaust counterparts is that they feature wider diameter piping and they increase the exhaust scavenging by simply aligning the exhaust pulses more optimally.

Catalytic Converter

The catalytic converter is the part responsible for allowing you to still breathe while you’re in Melbourne, Sydney or any major city that’s packed with vehicles. It takes the toxic emissions released from the engine and transforms them into less harmful emissions before releasing them into the atmosphere. High-flow aftermarket catalytic converters are much more efficient than regular converters, which basically means that the gasses pass through them much faster before they’re being moved further down the system.

Muffler

Even though there are many different types of mufflers on the market, they all have the same goal – to eliminate noise. One of the most common methods mufflers use to accomplish this is by redirecting airflow through porous pipes which make gasses expand into the sound deadening material that they’re made of. However, aftermarket mufflers aren’t always made to reduce the noise. In fact, some models are designed to make your Isuzu sound louder and more aggressive.

Pipes

The pipes that connect the manifolds to the catalytic converter, the catalytic converter to the muffler and the muffler to the exhaust tip (which is the last part of the exhaust system) all play a crucial role in the transportation of the gasses. Stock pipes are usually made with mild steel, whereas aftermarket exhaust pipes are made with aluminised or stainless steel. Further, aftermarket pipes are wider in diameter, which allows for an improved gas flow. However, bigger pipes aren’t always better, so make sure you buy an exhaust system that’s made for your Isuzu’s particular model, make and year to ensure a proper fit.
