Description
The Flowmaster 718111 is a FlowFX 409 stainless steel cat-back exhaust system designed for Chevrolet Silverado and GMC Sierra 2500HD and 3500HD trucks with the V8 6.6L gas engine. The 3.0 in. mandrel bent tubing with 3.5 in. inlet ID maximizes exhaust flow.

All factory hanger locations are used for a bolt-on installation. Backed by Flowmaster's Lifetime Limited Warranty.
