Dynomax evolution is on..... And loving it!!!!!
This is the kit that dumps before the rear axle, #39522. It was installed on a 2012 JKU Sport , automatic , with 3:73 gears and 35"
Got it from Amazon Prime for $178 then have to send in for the $50 rebate, so $128 in the end.
Ordered Sunday, came in today. Old exhaust off and new exhaust on all in 45min!!
Here is all the parts in the kit
The Intermediate is even notched, like the factory pipe, so it only goes on one way when slipped onto the "Y" pipe.
The clamps are solid and everything fit like a champ.
I did not trim the lip off of my EVAP skid for the rear hanger bracket.
DO NOT CUT THE INTERMEDIATE PIPE AS STATED IN INSTRUCTIONS
DO NOT
DOOOOO NOOOTTTTT
So the PROS....
Its great value.. at $178 you can't beat it
Its easy as pie to install
No drone on the highway, only drone is from 1300-1500rpms and thats it, it goes away.
No smell inside the vehicle when stopped
You free up all that area under the rear of the Jeep.... It looks so much better
Major smile on your face while driving.
The sound is amazing!!! Its not a V8 sound, but then again, it don't sound like a 6cyl
And the wife test drove it to the gym and when she got there, she texted me with ..quote..." IT IS TOTALLY AWESOME!!"
Now the CONS...
The outlet of the muffler could use a notch in the pipe in order to clamp the turn down better. I did feel like adding the relief cuts. Plus I was using air tools, so it pulled the clamp down tight, but someone doing it by hand...it'll be tough
Thats it for the CONS.
BYE BYE
Much nicer
Barely peaking out...

Congrats! I have experienced the drone at 1300RPM too. I actually like it. If I'm cruising that slow, I wan't to rumble to hell out of my jeep. ESPECIALLY with the doors off.

x2.
i have their dual tip axle back exhaust (forgot the part number) and I'm thinking about swapping out for this one. The one I currently have is pretty loud inside the Jeep but not too loud outside. How's the noise on the inside?

The drone from 1300-1500 is quick and you will feel it through the Jeep, like bass. But it's such a short duration, it's not a issue
As for videos... Check out Wayalife... He's got a really good video showing all driving conditions.
I don't have anything to post videos to and would have to record w my phone, which wouldn't give it justice :(

Going down the hwy in OD , turning 2k rpms... You can barely hear it. The lightbar on the windshield almost makes more wind noise than the exhaust note.
