This is the 4 door 2012 JK Evolution Competition system.
This system will dump before the rear axle.
I will know this weekend if it will work with a 2door.



Here is the "rock crawler" system for both the 2012 2 door and 4 door.
This system tucks the muffler out of harms way and clears up the rear of the JK.

Looks great! Glad to see these finally available, nice work Dynomax!!

Will there be any way of getting the rock crawler system with the VT muffler?

Dynomax

Every time I get this question (and it is a good one) I forward it on to my boss.
The one thing that we encounter a bit is that taking this muffler and placing it in the "rock crawler" space gets a bit tricky, but I have seen a few JK's use this muffler under the JK in front of the rear axle (use the OVER 4.0 application)

Well, if the kit doesnt fit the 2 door model.

That muffler will and then a local shop can fabricate something on the fly.

Great to see off road crawler kits now!!!

Since I have a 2012 Jeep Sport S in 2 Door style. I will post the question here in case others are interested.

My Jeep appears to have 2 mufflers.
1. the front is the resonator
2. the rear is the muffler
3. will deletting one of them from the system make them not CARB Legal?

So, you replace the one on the side beneath the drivers seat with the Dynamax 16in Oval one and cut after the axle and just disregard and delete the rear muffler beneath the tailgate altogether?

What is suggested retail for the Evolution competition system? Is it ready for purchase?

Is the only difference clearance between the two systems? Have you dyno tested and do you have real performance numbers for the 3.6?

im sorry to kinda hijack the thread but speaking of vt mufflers i got mine for my jk but the one for under 4.0 not realizing that the jk is special, so i called summit and they want me to send the one i have, back so they can send me the right one. the only problem with that is i wont have a muffler on my truck for a week. is there anyway you guys at the actual company can help me out?

Dynomax

Retailers are starting to carry these systems now.

The differences is where they dump.
In regards to dyno that is something on our list, other systems for the old engine saw mid single digit HP and TQ.

Sorry about this, we go through our retailers on stuff like this.

I'm highly interested in the Evolution Competition System but I have a few questions about it.
First is, why is it for Off-Road use only?
Second, do you know if that would void the powertrain warranty?
Third, is this a strictly bolt on kit or does this require welding?
