    Introducing Flowmaster®'s American Thunder® cat-back exhaust system for 2020 Jeep Gladiator trucks with the 3.6L engine. The mandrel-bent stainless steel exhaust system has a large 3.00-inch inlet tube flowing into a Super 44™ Series muffler providing a deep moderately aggressive exterior sound with a moderate interior tone. The 2.50-inch mandrel-bent dual tailpipes are routed to clear the factory spare tire and exits behind the rear wheels for a muscular look and sound. The tailpipes attach to the factory hanger locations for easy installation and are finished off with a pair of 3.50-inch polished 304 stainless steel tips embossed with the Flowmaster® logo.
