Exhaust - Downpipes w/X-Pipe (JHM-FI) for the B8 S5 3.0T and 4.2L FSI


* Required Fields

JH Motorsports is proud to offer the JHM/FI B8 S4-S5 Downpipes with X-pipe!

Built as a direct OEM replacement, our Downpipes with X-pipe are easy to install with simple hand tools; no cutting or welding required. Our X Pipe is designed to increase low end torque and maximize power throughout the entire RPM band. The exhaust system is unobtrusive at idle and cruising speeds; but comes to life at wide open throttle.


There is a lot of confusion surrounding the B8 S4-S5 Exhaust System Setup mostly due to the current "brand-x" systems available on the market. The B8 Exhaust can be split up into 5 parts. Starting from the outlet at the cylinder head you have the exhaust manifolds, the cat or test-pipes, the downpipes (this includes the x-pipe on the JHM B8-S4-S5 Full Exhaust System), and the remaining portion that includes the mufflers that exit at the rear of the car (sometimes this entire section is called the cat-back). See below for a diagram of the JHM B8 S4-S5 Exhaust System:
