At EJS, our muffler took some damage. Happened to run into Matt @DynoMax Exhaust and the vendor show and lucked out being able to get a dynomax muffler delete from him. As soon as we got home I put the Jeep on the lift to survey damage and install this delete pipe.

Only tools needed are a 15mm socket, wd-40 or similar penetrating oil, pry bar and rubber mallet. May not need all those but makes things easier.

Soak the rubber hangers in lube. While it’s soaking in break loose the clamp and make sure it’s loose. Also spray some lube at the clamp to help it slide off.

I used a 24’ pry bar on the drivers side to slide the rubber hanger off the frame mounted side. On the passenger side, you’ll need to push it off on the muffler side as the frame mounted hits the rear cargo tub. For that one I just pushed it off.

Once it’s free from the hangers, just take your time and work the muffler pipe off the exhaust. Takes a little wiggling but working it back and forth and some gentle motivation from a rubber mallet makes short work of it.

Once its off, get the new delete pipe and place the clamp loosely over the pipe. Slide it into place, grab the rubber hanger from the drivers side of the muffler and install it on the delete pipe. Once it’s all lined up, tighten the clamp.

How’s the sound? Much drone?
Baseball game was cancelled tonight so didn’t get to do a distance test. Will in the morning. Just driving it around our place there wasn’t much of a difference. Sounds great and I’m in no way into a ricer sounding Jeep

Went for a drive this morning and love it. Was worried it would be to “fast and furious” but I love the tone and depth. Sounds good when you get on it. Another benefit is getting rid of the restrictions in the factory bend and muffler.

I can try. Sound clips are usually hard to show an accurate representation of how it is in person. The benefit of this is for wheeling. The sound and power (if any) are just a bonus to me.

Thanks, I was concerned about any droning. I read DynoMax announcement thread and it seems like reviews were mostly positive.

At the price, it might be worth trying, esp if it gets rid of the stock exhaust

I did this muffler delete and couldn't be happier. BTW, I did MOAB too. Love the E.J.S.
While we didnt enjoy the trail runs organized thru ejs as much due to the lax vehicle requirements which made them long and painful to watch we enjoyed the event. We did some JL runs and had a blast. The event is awesome and while we didn’t win anything the raffle was a trip!

I assume that a muffler delete is not legal in all states?

Ya know I’m not sure. It’s not removing any federally mandated emissions equipment. Just the muffler so if your state has a law against modifying the exhaust I guess that would be a problem but never heard of any

I think that sucks for us in MO :) BUUT, this would be more of a trail config.

Maybe if you have some crazy sound decibel level laws. That's the only reason I would see, but many cars and trucks in stock form are louder than this seems to be.

Might take about 10-15 mins to swap over.
