A Vauxhall Insignia 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 Vauxhall Insignia 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 Vauxhall Insignia performance exhaust will also help give your machine a satisfying roar.
