Product Description

Introducing the JHM-FI B8-S4 3.0T FSI (24v) *TRUE* Cat-Back Exhaust!!!

Developed in conjunction with our friends at Fast Intentions, we are proud to offer the FULL Cat-Back Exhaust for the B8-S4 3.0T FSI (24v) featuring mandrel bent, 2.5 inch stainless steel piping and downpipes with X-pipe. This is a high-performance exhaust system that is essential to getting the most power out of your S4.

This is our JHM FULL Cat-Back Exhaust. This system will bolt right up to your OEM cat-pipes or JHM Test or Cat-Pipes and includes downpipes with our X-pipe, along with the center exhaust section (resonated or non-resonated), and finally the rear muffler sections featuring quad-tip outlets.

EXPLANATION OF THE B8 S4-S5 EXHAUST SYSTEM: 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 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:

FITMENT: Fits all 2009 and up B8-S4s with the 3.0T FSI V6 (24v).

- RESONATORS: Select your choice of resonated versus non-resonated exhaust from the dropdown menu below. Adding resonators to your cat-back exhaust will take the edge off any "raspiness" that an otherwise un-resonated system would have.

Comes with all hardware needed for a complete installation:
