I just installed one on mine. Seems to be a pretty good kit. I went with the 3" with high flow cat and flo pro muffler. Sounds really good. It has a nice growl but not to the point that it is obnoxious. I have had it up to 60 and there is 0 drone so far. I did ad my own hanger at the end of the muffler to suck the exhaust up as high as I could.

ive got it also, i went with the cat, the super 40, and 2.5"

ive had no issues other than the tail pipe spinning because of a clamp. ive welded it a bit and have had no issues now. its a good quality set up, shipping was quick and it came with everything you needed minus a new rubber hanger. that wasnt a problem since a got a new one to tuck it up as high as i could too

Nice! Are you planning on welding it or just running it with the clamps?

i'll clamp it in at my place then drive down to my buddies and weld it in. or drink. or something like that. mostly we'll drink.
and then readjust it cause i bet it shifts on the drive down, then weld it. lol

I have iro exhaust on my ZJ but i went with 3" Magnaflow 3" flowmaster 40 3" and 3" exhaustpipe.
Was a pain to install it without a lift tho..
had to remove the driveshaft, loosen the trackbar, handbrake wire bracket and the shock to get enough clearance to slide it in and it had to be done from under the jeep.
And i had to replace the brakeline to the right rearwheel because i broke it while trying to get the exhaustpipe in...

I have a video of it somwhere, there you can hear how it sounds.

Really?? I have the 3" as well and I only had to remove the tire. I will say it was quite a pain fishing the tail pipe around the tank and track bar tho. I do have a different track bar and a 3.5 lift. Maybe that was the difference maker.

If you jack it up and droop the axle it helps 4500%

Done and done quick and painless install.

The muffler I got is the performance one VX series or whatever. Not the flow master. It sounds mean. Little loud to but what can ya do?
I like it
