Product Description

The factory exhaust system holds your truck back more than most people realize. Tight piping, smaller diameter, and heat buildup all work against performance. This Banks Monster Exhaust replaces that entire restriction with a full 5-inch constant-diameter system that dramatically improves flow—up to 85% less backpressure than stock. That means your engine can push exhaust gases out easier, helping it make more power, respond quicker, and even improve fuel efficiency. On top of that, the SideKick tip design actively helps pull exhaust out, creating a smoother, more efficient flow path.

But this isn’t just about power—it’s also about solving real-world problems. During regen cycles, stock exhaust systems can blast extremely hot gases straight back, which can damage trailers or anything behind you. Banks fixes that by directing exhaust out to the side, allowing heat to dissipate safely while also reducing temps by up to 15%. Add in the massive ob-round tip that stays clean without discoloring, plus heavy-duty stainless construction, and you’ve got a system that performs as good as it looks. This is one of those upgrades where you don’t just feel the difference—you get better efficiency, safer towing, and a setup built to last.
