2011-2014 Duramax Exhaust System Kit (47786)

Description

Fits

The Banks Monster Exhaust is engineered using computational fluid dynamics (CFD) software then tested on both dyno and on-road to make that Duramax sing and lay down impressive numbers! The Monster Exhaust system cools while flowing up to 80% better than stock! Cooling without killing flow is a major challenge. But the Monster Exhaust wins on both counts thanks to its mandrel-bent constant-diameter tubing and huge Ob-Round patented SideKick tip. The tip is the key. Its unique shape mixes hot exhaust gas with cool ambient air. And, it keeps your trailer safe by directing exhaust gasses to the side.
