RallySport Direct is proud to provide you with a large catalog of quality automotive performance and cooling products brought to you by Mishimoto. 

 

Here, you are looking at the Mishimoto Catted Downpipe. This is a nice upgrade that replaces your factory pipe that is heavy and restrictive, and the Mishimoto unit has been designed with smoother bends and a larger piping diameter. The result is more horsepower and more torque, along with improved engine response.
