This durable, purpose-built, cat-back exhaust system for the 2018 Jeep Wrangler JL 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 unique pre-axle turn down tip handles 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.
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
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.
This part does not require a CARB EO
All aFe exhaust systems are engineered and manufactured in our Corona, California facility.

After a shipping fiasco (thank you, FedEx), I finally got this and installed over the weekend. I think I can safely say that it couldn't be easier to install. I'm no mechanic. I just followed the video on CJ Pony Parts. The hardest part was getting the stock off. Even after just a few months, it had its fair share of rust.
The new exhaust is actually a good bit louder than I expected, especially at around 1500rpm. It does sound a lot better than stock; just a bit loud. I'll see how it feels as time goes on.
I definitely prefer the more or less invisible look. The big stock muffler on the back just kinda looks silly to me, and of course, it's nice to have this new one more up and out of the way for clearance.
I can't say I definitely can feel a performance increase, but it does give the sense of going faster--probably just due to the sound. When you step on it, it's like driving the race car you imagine as a kid (sound wise), going thru each gear. Vroom vroom.
