Review on πŸ”§ TOTALFLOW 20320 Straight Through Universal Exhaust Muffler - 409 Stainless Steel - 3.5 Inch Inner Diameter Inlet/Outlet: Enhanced Performance and Durability for Optimal Exhaust Flow by Mike Diaz

Revainrating 5 out of 5

Sounds good! Best in Exhaust and Emissions

Used to replace the stock muffler on 2018 Sierra 2500HD 6.0. The sound is amazing! The drone is minimal, with a nice aggressive growl at the throttle. 100% build quality, fit and finish. I used a shortened model on my race car (Turbo 6.0) so I was dying to install it. I'm glad I rode full power for the second time
