cp-e™ QKspl™ BMW N54 Catted Downpipes
cp-e™ cast stainless downpipes have been designed specifically for the n54 motors to reduce back pressure and optimize exhaust flow.
cp-e™ QKspl™ Ford Fiesta ST ECOf™ by GESI® Catted Downpipe
Although more power and great sound are high priority items when buying a 3″ downpipe, the fine details are what ensure that the product will satisfy the end-user for a lifetime.
cp-e™ QKspl™ Ford Focus ST ECOf™ by GESI® Catted Downpipe
Following the same successful recipe we have used for our other downpipes, our Focus downpipe replaces the choked factory pipe and its restrictive cat. The result of our efforts is reduced backpressure, decreased turbo spool time, and improved dyno results – more than 5% gains.
cp-e™ Triton™ BMW 1M Exhaust
The exhaust note of a vehicle defines character and presence. BMW engineers the ultimate driving machines and the 1M has been their latest creation.
cp-e™ Austenite™ Subaru WRX Off-Road Axle Back Exhaust ('15-'20)
OEM parts often times are designed for efficiency of manufacturing, cutting costs and driver comfort. Unfortunately performance is often not a priority – as seen on the very restrictive factory WRX axle back exhaust setup on the 2.0L motor. The boxer exhaust from the factory totally hides the sound of the car. With the factory exhaust, you might as well be driving a vacuum cleaner. The first time we started up the WRX, we knew that we had to uncork the boxer exhaust.
cp-e® 1.6t Gamma QKspl™ Cast Bellmouth Downpipe
cp-e™ QKspl™ Ford Focus RS ECOf™ by GESI® Catted Downpipe
Following the same successful recipe we have used for our other downpipes, our Focus downpipe replaces the choked factory pipe and its restrictive cat. The result of our efforts is reduced backpressure, decreased turbo spool time, and improved dyno results – more than 5% gains.
