After running the muffler for a week or so, I decided to remove and replace the factory muffler. The sound is unique and definitely adds something to the Jeep that a factory muffler can not. However, the sound is just not for me. As Jeep owners know, the internal isn’t as air tight and external sounds come through. With the increased rumble at acceleration and higher RPM’s the noise is just overwhelming to me. That being said, the initial 2 hour install was cut drastically down to 30 minutes to switch out the new with the factory exhaust.
It took a little longer to get around to the actual install, but I’m happy to say that after months of sitting on this mod the Deegan 38 Gibson Split Rear Axle Exhaust has announced its presence. If you’re anything like me the look of your Wrangler is one of the utmost importance. The dingy worn out factory muffler sticks out and down (unless you have a sand tone paint job).
So, let’s start with the boxing! Heavy and if not carefully handled, the mount can and will push through the box and could be damaged along the way. Luckily for me, our delivery was in great shape.
The install of the Deegan 38 Gibson Split Axle Exhaust presented a few hurdles to get over, but overall the install took just under 2 hours. The first thing I had to do was remove the factory exhaust, which took a majority of the 2 hours. Depending on the level of rust that your factory exhaust has will ultimately determine how hard it is to remove. Luckily, mine wasn’t rusted, but instead the rubber mounts hangers.In order to properly remove the exhaust, you will need a 5/8 socket, WD-40, channel lock wrench, and a possible pry-bar.
The Deegan 38 Gibson Split Axle Exhaust itself was 4 bolts to install and honestly very easy. The biggest test was the sound. The initial start of the engine was exciting and different. The exhaust provides a rumble that the factory Wrangler just won’t provide. Take a listen to the before and after clips of the factory exhaust and the new Gibson exhaust.

A little about the Deegan 38 Gibson Split Axle Exhaust based on the details provided on their site.
- Aggressive Exhaust Note with Minimal Drone
- Improves Exhaust Flow for More Power
- Dual Outlet – Straight Through Muffler Design
- 2.5″ Mandrel-Bent Aluminized Steel Tubing
- High Temp Black Ceramic Finish
- 4″ Intercooled Round Slash Cut Exhaust Tips
- Direct Bolt-On Upgrade
Overall, the exhaust definitely changes the sound and even perception of the Jeep. The look is streamlined with the black on black and dual pipes. The install was easy to moderate. I would recommend if you want to change the rear look and sound to check out this exhaust. The sound is something to get used too, but I like it thus far. Be warned though, this isn’t a trail ready exhaust for hard trailers. This will work on moderate to easy trailing, but rock climbing is not recommended and will damage if hit hard enough.
