This aFe Mach Force XP 5" cat-back exhaust systems enhance smooth airflow from the catalytic converters, all the way to the huge polished 304 stainless steel tip. The 5" 409 stainless steel tube construction provides a long lasting finish and maximum air flow for those high powered Cummins. This system features bayonet style hangers to hold hangers in place better than traditional rod hangers. aFe Mach Force XP exhaust systems also feature band clamps that have a much stronger sealing area than the standard U-clamps used on other systems. This system is 50-state legal as no OE smog equipment is modified.

Either way you slice it...This system is the baddest cat-back system you can buy for your Cummins.
