Has anyone tried the Cool Tech kit to relocate the exhaust on the 4 door unlimited. Any problems with the new location.

 

I have it
pretty straight forward install
the hardest part is getting the #%&@ hangers off!
do not use WD-40, use silicone
also on the front piece, when you connect it back up, make sure the screw fits up into the notch, otherwisee it sits far enough back to cause rattling
I does sound good, and get better with age

 

I installed it about 2 years ago. No trouble with the install and no problems since the install was done. Jeep is louder and it's hard to hear conversations spoken from the front if you are in the back seat. But I don't sit back there.

 

None...Been running mine for over 1.5yrs now...

 

Had mine for over a year now. No problems what so ever. The install went smooth, just pay attention to what you are doing. The sound is not that loud at all, has a deep growl and crackles when coasting

 

Over a year for me and it is great. Install was easy took about 1.5 hours by my-self.

 

Looks good, but I would demolish that without a skid!
