$2,200.00

Introducing the JHM-FI B8-S5 4.2L FSI V8 *TRUE* Cat-Back Exhaust!!!

After months of development and testing on our in-house 2008 B8-S5, we are pleased to announce the release of our FULL Cat-Back Exhaust for the B8-S5 4.2L FSI V8 featuring mandrel bent, 2.5 inch stainless steel piping and our JHM Downpipes with X-pipe. Similar to the highly successful JHM-FI Cat-Back for the B6-B7 S4, we worked with Fast Intentions to develop this B8-S5 4.2L V8 Cat-Back, too. The result is another high-performance exhaust system that is essential to getting the most power out of your S5.

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 JHM 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.

This exhaust system was featured on our car during the record setting quarter mile passes of our in-house B8-S5:


Here's a video with a sampling of audio clips for the Full Cat-Back on an S5 with our 2.5" Downpipes:

Here is another video highlighting the sound of our Cat-Back featuring our in-house B8-S5 making some launches at the track and during normal driving:


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-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:

FITMENT: Fits all 2008 to 2013 B8-S5s with the 4.2L FSI V8 (32v).

OPTIONS
- 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:
