Exhaust – COMPLETE High-Flow Cat Downpipes (JHM Combo) for the B8 S5 4.2L

JH Motorsports is proud to offer the JHM B8 S5 4.2L Complete High-Flow Catted Downpipes Combo!  

NOTE:  This downpipe version is necked down to fit the STOCK/OEM Catback.   If your Aftermarket Catback fits stock downpipes (AWE for example) This is the option you will need.  If you have custom 2.5″ catback connection, please see our non necked down version.    Just because the system is 2.5″  doesn’t mean the connection is.

 NOW SOLD AS A COMBO!

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
-Direct OEM Fitment without modification
