JHM RETROFIT SERVICE - Exhaust - Integrated Baffle System for the JHM - X-pipe B8 S4-S5 Q5-SQ5 C7 A6-A7 3.0T and 4.2L FSI

***NOTE: THIS IS THE RETROFIT SERVICE FOR CUSTOMER WHO ALREADY HAS OUR DOWNPIPE X-PIPE WITH HFC***

** INTEGRATED BAFFLE SYSTEM **

The Integrated Baffle System Version of our JHM HFC Downpipes w/ X-Pipe is for those who are looking for a quieter exhaust system. The baffles have been designed and strategically located in the downpipes to reduce unwanted drone and rasp (Depending on your catback, results may vary).  We used popular exhaust systems for our trials (AWE Touring & Track) along with our JHM Race Pipes and were able to get the interior noise down to just 70db while cruising at 70mph in 6th gear at 2500RPM with the JHM Baffled Downpipes.  That is 10db quieter than the AWE Touring and 15db quieter than the AWE Track systems WITHOUT the JHM Baffled Downpipes installed.  During our testing, at 70db we heard more road/tire noise than exhaust.

(Tested on a B8 S4 6-Speed Manual)
