Saw those about a month ago, tempted to swap out but Im not looking forward to going back and butchering the rest of my exhaust to make it work. If there was some real gain, maybe. Im really not sure how they get the runners down on the passenger side. Its tight there with a single 3" piece of tubing and that was after cutting off part of the upper control arm mount.
Put the full Kooks set up on mine about a month ago... been too lazy to start a thread on it.
Went with 1 7/8, catted y-pipe, and their cat back. Absolutely fantastic fit with my MoTech LS3 swapped JKUR.
There is no hiding the fact that this Jeep is housing a beast of an engine any longer, but at cruising speeds 55-85 there is no drone and it is quiet enough for long trips. Put your foot in it and well, it’s loud.
Power gains are noticeable throughout with no tuning adjustments. The engine revs noticeably more freely while really seeming to pick up some torque below 4,000.
I’ll get around to starting a thread tonight.... just calling it quits on day one of the TSP cam swap
Will tune/dyno and update my non-existent thread on this in the next couple of weeks.
