Product Description

Introducing the JHM-FI B8-S4 3.0T FSI V6 (24v) Cat-Back Exhaust!!!

**NOTE: This is the PARTIAL Cat-Back Exhaust for the B8-S4 with 3.0T FSI V6. This exhaust system necks down to stock piping size of 2.35 inches and connects to the stock resonated downpipes (which connect to the OEM cat-pipes). For more information on the B8-S4 Exhaust System, see our diagram below.**

Developed in conjunction with our friends at Fast Intentions, we are proud to offer the Partial Cat-Back Exhaust for the B8-S4 3.0T FSI (24v) featuring mandrel bent, 2.5 inch stainless steel piping.

Note: This video features a B8-S4 3.0T with our FULL exhaust system.

This is our JHM PARTIAL Cat-Back Exhaust. This system will bolt right up to your OEM resonated downpipes and includes the center exhaust section (resonated or non-resonated) and the rear muffler sections featuring quad-tip outlets. If you are interested in our FULL Cat-Back Exhaust System, please go back one section and select that 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.

NOTE ON BUILD TIME: This exhaust system is made to order and has a lead time of about 4 to 6 weeks.
