aFe® (18-23) Wrangler JL ROCK BASHER 3" 409SS Cat-Back System

This durable, purpose-built, cat-back exhaust system improves clearance over rough terrain for the adventurist who wants it all. The 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 offering a unique pre-axle turn down tip to clear any off-road obstacles. This system utilizes factory mounts for a quick and simple install.

Unique Pre-Axle Turn Down Tip:
This cat-back exhaust system has a turn down tip under the vehicle, before the rear axle, to take on rough terrain and off-road obstacles. No more smashed or lost tips to worry about.

Aggressive Sound:
A free-flowing stainless steel muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque.

Installation is a Snap:
This exhaust system uses all factory mounting locations, and quality hardware for a 360-degree sealing surface and hassle-free installation

Perfect Fit:
Factory style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The bayonet tip holds the hanger bushing in place for a long lasting, factory style fit.
