17-19 GM 6.6L Duramax Banks Power Single Monster Exhaust System

Fits: 2017-2019 GM 6.6L Duramax L5P (All Cabs & Beds)

Get rid of that ugly stock tailpipe and reduce backpressure by 57% on your L5P Duramax with this easy to install exhaust upgrade from the professionals at Banks Power.

Reducing backpressure allows the engine to expel spent gasses with less effort. Less pumping loss means more horsepower, lower EGTs and improved fuel economy.

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. It's unique shape mixes hot exhaust gas with cool ambient air. And, it keeps your trailer safe by directing exhaust gasses to the side.
