This Flowmaster(R) American Thunder(R) cat-back exhaust system for the 2021-2023 Jeep Gladiator trucks with the 3.00-liter diesel engine is manufactured using durable 409 stainless steel throughout and features 3.00 inch mandrel bent pipes for better exhaust gas flow.

Maximum dyno gains of 3 hp and 5 lb.-ft over stock were measured at the rear wheels. This system exits with a 3.00-inch polished stainless steel tip for added style and a custom look. The system uses all the existing factory hanger locations and includes installation instructions and all necessary hardware for an easy installation that you can do at home.
