The way their system is designed it isn't going to happen, that is why we have our Evolution Competition System for the JK.
We also offer it for the 2012- models as well.

 

Dynomax- what has been the complaint with the axle back?

Anyone have sound clips online for the 12 models? Cat back vt, or axle back?

I was originally drawn to the afe for looks and tuck of the muffler, but after reading and listening I think it is louder than I want.

 

So around $70 for the muffler only on a 39523 kit. Which means the other $280 is tailpipe and a few clamps.....mmmmmmm, Dynomax, got a tailpipe part#?

 

I have had a few people complain about drone, but more people are happy with it than not.
Some people don't like how one of the exhaust tips hangs down a bit (this is done to get condensation out of the welded muffler), but we have tweeked it back up now, so that it doesn't hang as low.
It is a much more compact free flowing design than the stock bulky muffler.

Also message me your e-mail, I have a sound clip of the AXLE back.

Enter 39523 and you can find the P/N's.
Remember these don't build themselves, there is an engineer that designs these, and other associated costs with making a system. That being said, a lot of guys just get the muffler and make their own system.

 

@dynomax do you have a pn for the muffler used in the 39522 kit?

 

P/N 17263.

 

Thanks! Just ordered the muffler from advance auto!

 

Question regarding Dynomax Rock Crawler for a 12' 4-dr has anyone had any drone issues?? Also anyone running the MBRP any drone issues??

 

I haven't heard this exact system on a 12- yet, but I have heard it a lot on our 2007. I could make it drone ( I can make almost any muffler drone LOL) in the high 60's low 70's, but the tire roar and soft top flap was more annoying honestly.

 

Dynomax, thanks, yea it was a bit tongue-in-cheek really and I do understand the process. Don't mean to come off as cheap (even though that's what I'm doing) but watching those same kits go for around $100 after rebate for the earlier models ruined it for me to pay $350 for this one!
