Injen is well known for their intakes, but most do not know that they also offer exhaust components. The Evolution downpipe is a perfect example of this and is one of the highest quality on the market. It uses 3" mandrel bent stainless steel piping and will bolt up with stock or aftermarket exhausts. A downpipe like this free's up exhaust flow and adds power and throttle response. This downpipe will cause a check engine light as it is completely catless.
