  • A downpipe is one of the first modifications that should be done on your car, as the OEM downpipe contains two very restrictive catalytic converters. Replacing these with their single high-flow unit will dramatically improve performance potential while maintaining the use of a catalytic converter. This downpipe is Proudly made ins the USA using CNC Flanges and 304 steel for a lasting product. along with a divorced wastegate for optimum flow also include and extra O2 Bung for an aftermarket wideband should you have the need. Gaskets for both sides of the downpipe and hardware are included.

    NOTE: Once you have added a downpipe to your vehicle, you must be tuned. Replacing your factory catalytic converter sometimes causes a ‘cat converter efficiency’ check engine light. You can either use tuning to delete this CEL or you can use a mechanical fix. GrimmSpeed aftermarket downpipes modify OEM emissions control devices and are intended only for off-road racing applications.
