Product Details

This downpipe is constructed of tig-welded 16-gauge 3" mandrel bent T304 stainless steel tubing. A 3" stainless steel High Flow 400 cell count catalytic converter is built-in, three stainless steel oxygen sensor fittings, and a stainless steel OE style flex joint into our design. The connecting flange is 3/8" thick laser-cut stainless steel. Dyno tested to give you a gain of approximately 10-12 WHP and 15-20 WTQ. This is a bolt-on two piece design, and downsizes to fit the stock system or a 2.5" performance exhaust system. Backed by a 6 month warranty against manufacturing defects and workmanship.

**Note: Some vehicles may have a check engine light with this downpipe because of the high flow catalytic converter, this may be resolved with ECU programming.**
