** INTEGRATED BAFFLE SYSTEM VERSION **

The Integrated Baffle System Version of our JHM HFC Downpipes are 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) 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. Note:  The main purpose of the Integrated Baffle System is to combat unwanted drone and take the edge off rasp. 

Built as a direct OEM replacement, our JHM Catted Downpipes are easy to install with simple hand tools with no cutting or welding required. Our Downpipe is designed to increase low-end torque and maximize power throughout the entire RPM band. Moving the Catalytic Converters further downstream into the downpipes, we are able to take full advantage of our JHM B8 2.5″ Pipes and alleviate heat build-up close to the engine, increases Catalytic Converter longevity, as well as overall engine performance.

Features:

-JHM High-Flow Cats located further downstream
-JHM V-Band Downpipe to Midpipe Connection for easy install
-JHM Integrated Baffle System
-Direct OEM Fitment without modification
