GMC/Chevy, 2019-2026, 6.6L - MPI Bullnoze Exhaust Series

The all-new MPI Bullnoze exhaust series fits your 2019-2024 GM 6.6L, providing a Deep, Aggressive exterior sound while keeping the interior sound without that drone! The turn-down tips in front of the rear end look like a bull getting ready to charge! 

This series still gains those huge MPI Performance numbers; This bolt-on emissions-legal system features all mandrel-bent tubing built in Montana. 

Dyno Results: Test vehicle dyno gains of 16 hp and 20 lb-ft at the rear wheels over stock. Most Vehicles are gaining 2-4 MPG. These numbers are with zero tuning, versus a Stock truck. 

Muffler Options  :

MPI Performance series mufflers are going to be more aggressive-sounding 

Quality: MPI Exhaust Kits use the highest quality 14 Ga. Tubing. This extra-thick tubing is proven to last in harsh environments, including road salts and rough gravel roads. It is perfectly protected with the best anti-rust coating mankind can make. Backed with our 3-Year Limited Warranty, we stand behind what we build!

Note: All our kits are produced for the truck's longest wheelbase. You may need to trim your kit, and the complete instructions provide all the necessary measurements to make it a perfect fit.
