Loop delete
Works great. I was able to install in less than 20 minutes. Foe some reason my exaust was rubbing the frame and hard to get lined up at the y pipe. It solved my issues and sounds great too

Axle Back Exhaust
I am over all pleased with this exhaust. The install was easy and quick (20-25 min... getting the old exhaust off took most the time)with the right tools. The sound is great and not to loud. When you fire up the Jeep it will make you smile. The sound while on the gas is noticeable but not crazy. I added the AFE throttle body spacer and cold air intake. I'm not sure if i can tell a performance gain because of this... but it sounds great and looks good.

Great Jeep Muffler
I really like the way it sounds...it just right...not too loud or not enough sound. Plus like the fact that it sits up high and is hardly visible from looking at the back of the jeep.

AFE Rebel Series Axle-Back Exhaust System with Black Tips
These look and sound great! Have not been able to run the Jeep enough yet to get full impact of performance gain, but I love them.

Great sound
Pros Super easy to put on and lightweight high tuck. Great sound with no roof/windows open Cons With windows shut and a hardtop the cabin noise is VERY annoying around 2000-2500 rpms.

Great fit and sound for my 2016 Willys
Easy install and great sound! The product description says it’s moderately loud but I find it on the low side of moderate… which is perfect and not obnoxious.. Also 1/2 the size of OEM exhaust and tucks up nicely.

Perfect Sound!
Easy install number 1. I cannot say the removal was easy. My wife’s jeep spent some of its life in PA, so unfortunately the old clamp had rusted onto the muffler connection to the rest of the exhaust making a difficult removal. But I was still able to do it using only a ratchet set and some WD40. Now sound. It really sounds good for a V6, I’ve owned Audis and Chevelles and everything in between and this thing is up there with the sound. Throaty but not too high pitched. Really Subtle until you step on the gas. As far as any performance gain. We have an 87 Octane tune from the flashpaq tuner and a cold air intake, with the addition of this more free flowing muffler delete, I could feel a more positve throttle response. I cannot speak to what this would be like for a completely stock jeep, but for a more modified (tune/CAI) I think there is some performant can be squeaked out of it. I am not mechanically inclined at all, and I was able to do it on the ground with no lifts or jackstands 10 out of 10 would recommend this

Works on the 2.0L as well
Quick and easy 10 minute install and my Jeep is nice and loud now. I’ll be getting the muffler portion of the AFE system within the next few months as well but the muffler delete was a nice in-between addition.
