Product details

This durable, purpose-built, cat-back exhaust system for the Jeep Wrangler JL 2 door improves clearance over rough terrain for the adventurist who wants it all. Large, 3" mandrel-bent 409 stainless steel tubing outflows the restrictive factory exhaust to deliver gains of up to +9 horsepower and +8 lbs. x ft. of torque, as measured on our in-house dyno. The free-flowing muffler delivers a powerful, performance tone while the ROCK BASHER'S shortened pre-axle turndown tip handles off-road obstacles. This system utilizes factory mounts for a quick and simple install.
