RallySport Direct carries a large collection of automotive performance components to enhance your driving experience brought to you by cp-e.

 

These are the cp-e  QKspl Bellmouth 3-Inch Catted Downpipes. These downpipes have been designed to be direct replacements for the highly restrictive factory downpipes. The cp-e units have been designed by combining a larger piping diameter with smooth bends, as well as large cast bellmouths to provide the turbochargers with an unobstructed exit strategy for the exhaust gases. The result is an increase in both horsepower and torque, with an improvement in throttle and turbo response.
