AFE 01-07 Duramax Diesel Performance Exhaust 49-14003

This diesel performance exhaust system from AFE was built for the 2001-2004 LB7 Duramax trucks, but also works on the 2004.5-2007 LLY and LBZ Duramax trucks for off road use only.  This is a 4 inch 409 grade stainless steel system that attaches to the factory down pipe from the turbo.  To complete the kit a down pipe is available separately.  The exhaust tip pictured is sold separately.

This kit is built for all wheelbase trucks.  Shorter length trucks will have extra pipe left over.
