Description
The Flowmaster American Thunder Cat-Back Exhaust System is designed for 2020–2025 Jeep Gladiator trucks with the 3.6L engine. This high-performance system delivers a deep, moderately aggressive exterior tone with a mild interior sound, combining Flowmaster’s proven Super 44™ Series muffler with dual 2.50-inch mandrel-bent stainless steel tailpipes.
The dual side exit tailpipes are routed to clear the factory spare tire, attach to factory hanger locations, and exit behind the rear wheels for a muscular appearance and sound. The system finishes with dual 3.50-inch polished 304 stainless steel tips embossed with the Flowmaster® logo. Constructed from 16-gauge stainless steel, the American Thunder Cat-Back is built for durability, performance, and easy home installation with all necessary hardware and instructions included. The system is covered by Flowmaster’s Lifetime Limited Warranty.
