Subaru Impreza Exhausts

  • Downpipes


    Subaru Impreza downpipes are a popular upgrade for car enthusiasts that have turbocharged performance cars. They can help to give your machine a considerable boost in horsepower. Downpipes are a kind of exhaust that allows exhaust gases to flow into the exhaust system, away from the turbine housing. It is important that these gases can flow freely from the turbo housing because gas flow restrictions could otherwise affect spool-up times, and this can reduce performance. While most turbo engines are fitted with downpipes, they don’t always allow the exhaust to flow as freely as aftermarket options. A Subaru Impreza downpipe is designed to maximise the flow of gases. They will also incorporate a catalytic convertor of an advanced design to maximise air-flow, or even remove it altogether. While a downpipe will provide little to no benefit to cars with non-turbo charged engines, they can provide a significant boost to those with a turbocharger.
  • Manifolds


    Manifolds are one of the most often replaced parts in cars. Upgrading your Subaru Impreza manifold can also give you a boost in power. There are two main types of manifolds in cars: The intake manifold and the exhaust manifold. An intake manifold is important because it helps to supply the engine’s cylinders with a flow of oxygen and fuel that has already been mixed together. This then allows combustion to occur, powering the engine. An exhaust manifold collects exhaust fumes from the engine and allows them to pass out from the vehicle. A new Subaru Impreza manifold is often needed because the existing one has been damaged. In the case of an intake manifold, a leak can affect the engine’s supply of mixed air and fuel and this can lead to a decrease in power. An enhanced Subaru Impreza manifold can help to give you a boost in power by improving the removal of exhaust gases from the system.

A Subaru Impreza performance exhaust is one of the simplest of upgrades you can undertake on your car.

When your engine burns fuel, it creates fumes and these fumes have to have a way to escape. The exhaust allows these fumes to escape and they are a standard feature on combustion engines. Standard exhausts don’t always allow the fumes to pass out freely, however, and this can cause backpressure. This backpressure will limit how much more oxygen the engine can draw in, thus impeding performance.

A Subaru Impreza exhaust is designed to allow the maximum flow of fumes out from the engine. This, in turn, means the engine can suck in more oxygen to use as fuel, giving your engine a welcome boost in horsepower. A performance exhaust is also likely to be lighter, offering a further improvement on performance. A Subaru Impreza performance exhaust will also help give your machine a satisfying roar.
