Very good shipping and very little delay due to todays conditions. Exhaust fit perfect and sounds very nice.
The box arrived all beat up. After installing exhaust I noticed there was a hole in the muffler. Not happy
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.
1997 XJ 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.
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.
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.
