Flowmaster 818131 American Thunder Cat-Back Exhaust System

This Flowmaster® American Thunder® cat-back exhaust system for the 2021-2023 Jeep Gladiator trucks with the 3.0-liter diesel engine is manufactured using durable 409 stainless steel throughout and features 3.00-inch mandrel bent pipes for better exhaust gas flow. This system removes the muffler for an aggressive to moderate sound level and maximum performance, while also adding additional clearance when driving off-road. 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. Backed by Flowmaster's Lifetime Limited Warranty.
