This system replaces the stock muffler with straight pipe for an aggressive exhaust tone and increased performance. Maximum dyno gains of 12 hp and 13 lb-ft. were measured at the rear wheels. 3.00-inch mandrel bent 409 stainless steel tubing is used to maximize exhaust flow and durability. This system keeps the exhaust tip tucked up higher in the rear of the vehicle for better departure angle and minimizes the chance of hanging up on the exhaust when aggressively off roading. A polished 3.00-inch stainless steel tip is used to to add a custom look to this iconic vehicle. All of the necessary hardware is included and factory mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.
