What is J-Pipe?

A J-pipe is a downpipe that’s shaped like a J. It’s a higher-flowing pipe that leaves less backpressure.

Our quality products like high-flow downpipes include both application-specific or universal-fit models for many vehicle types. In addition to offering a number of downpipes from the industry’s best manufacturers (AMS Performance, Cobb Tuning, Invidia) at Modern Automotive Performance we also offer our own custom-made replacement downpipe parts and components.
