1997 XJ Sport, 5.5 Rubicon Lift, 33 BFG A/T's:
This system is obviously designed to fit a stock XJ as it should be. My Rubicon 5.5 lift has the longer rear spring shackles and I have a Skidrow gas tank skid plate which changes the space in that area. The ONLY issue I had during install was the rear hanger with the unit is a Ubolt clamp which didn't fit in the space due to my mods. Simple fix was to cut the clamp off the hanger and weld it to the pipe like stock. Other than that every thing lined up perfectly and doesn't rub or bang on springs or skid. A little better rumble over stock, a little better mileage, and a noticeable amount of horses in the seat of your pants. I'm pleased with the system overall.

Had to have a muffler shop weld it on for me. Not too loud but there is a little resonance at certain rpms. Seems louder at idle and about like stock on the road.
Would probably just have had my rusted out muffler replaced in retrospect. But I got suckered into the rebate.

Good deal, easy one person job
The system when on really easy. One person can get the job done with no problems. I was hopping for a louder exhaust note, but it is not bad, better than stock, but not anyoing to the neighbors.

Awesome product but needs better instruc
The product is awesome! It has a nice deep sound. Installed it on my 92 wrangler yj 2.5l. The only bad thing was that I had to buy a extra part to install the exhaust because I cut the old one to short.

Quiet until you want it not to be
So far so Good, nice subtle sound until you shire down on it then it opens up. We will see how it holds up after a few creek crossings.

Dynomax Cat back super turbo
Have the super turbo cat back system on my 1996 Jeep Cherokee. This was a replacement for the original rusted mufler. Added a mellow sound without being overly loud. It was easy to install. I do not like the angle of the tail pipe end as it rattles against the spring shackle.

more bang for your buck
This kit went on very easy its about as quite as stock exhaust but flows alot better, it helps keep the sleeper theme going and nice not wakeing the neighbors
