How about a CTC Cherry Bomb tucked up underneath neatly , not yelling here I am come and hit me.. and if it does then yu haven't lost much. My opinion of experience.. lol
Had a Cherry Bomb on my 97' TJ for awhile. Wouldn't suggest that to anyone! Wasn't on very long. just couldn't tone that thing down!

Have the Gibson dual tip muffler on my 2011' Wrangler. Nice throaty sound and gentle purr at highway speeds.
Basically the same setup as the Magnaflow.
Nice upgrade.
The GF can turn the radio up.

Attachment 2730Did my first performance modification last week, off course I'd pick the hottest freakin' day of the year to attempt it so I can truely say I've got some (serious) "sweat equity" into this mod.
Put on Magnaflow's Performance Exhaust System #15160 (name's a bit misleading, it's really only a muffler). Install is really idiot proof - the fact I did it proves it.
The muffler comes in a huge box that turns out to have enough form fitting foam to let the muffler survive an elephant stampede untouched! There are three parts, the muffler, a clamp and the instructions. The instruction were immediately discarded as "real men don't need no stinkin' instructions" Both tail pipes are weld right to the muffler.

Two vital items to bring to the dismantle - WD 40 and dishsoap.
Depending on how long your original mufflers been in place (mine since Dec 2010) spray WD40 on the clamp bolt. It's an unusual type with a curved head bolt which fits into guide you can't get a wrench on. The single nut on the bottem presses in a similar "washer head" in the bottem of the guide. Don't waste your time working the nut all the way off to remove or slide the clamp out of the way - YOU CAN'T! The clamp is spot welded to the muffler pipe.
Once you got the clamp loosened, move to the rubber hangers. Both your old muffler and the new Magnaflow use rods welded to them which press through the hanger rubbers with a big head on the end to prevent them from pulling back out. You've got some play to slide the rubber hanger back a bit. Do it and put the dishsoap on the head and as much of the rod as you can. With a pair of channel-locks, one jaw on the head and the other on the back of the rubber, press it out. Once you've got both hangers out, you can now twist the whole muffler on the pipe. Give the muffler a couple of twists to break it loose froom the pipe, then grab the WD 40 and spray it down inside the flange and bingo off it comes. (Well yours will, me I twisted and hammered and wiggled for 20 minutes til I thought of the WD 40, then it fell off on top of me!)
You can have the Magnaflow muffler installed in less than five minutes, (if you don't stop to wipe the sweat outta your eyes and "beer break"). Hit the rod ends with a little dish soap and they go right through the rubbers and the clamp the company provides is identical to the factory one so you don't even have to go after different sockets. There's no adjustments involve as the pipe is fixed and the rubbers stayed in the factor positions.
Then it's ignition time! Gave my jeep a real nice rumble a idle and a throaty bark under acceleration. That "bark" has costly me likely 2 or 3 kms of gas milage "cuss I just gotta hear it!"
Included some pic to help anyone thinking of making this mod.

I would really like to know what sort of performance increase you got with the new exhaust?

The honest truth of the matter is "I really don't know!" Without dyno testing a before and after no hard
figure is available in that sense. Personnal seat of the pants experience is the jeeps "feels" a little more
snappier, but that may be the result of the change in shifting pattern as I now rev the motor up to 3,000 to "embrace the rumble", where as before I usually was pullin' a gear just over 2000. Gas mile age wise,
I have three vehicles on hand at any time, and drive what ever suits my fancy or need on any given day - or what's got gas left to try to ride out the latest price jump, so it may take me a month to go through a tank of gas. I road tripped to Nova Scotia this year again but can't make an apples to apples comparison because the first year I trailered my Harley. That trip I can tell you the Jeep was a gas guzzlin' dog! To be fair though, my trailer hitch was dealer installed on a non-trailer packaged Sahara - meaning 3.25 gears not 3.75's. This combo IS NOT suited to mountain towing! Thank god for a 6 speed
manual - 'cuss I was rowin"!
Sorry I couldn't be of more help.
