Pretty excited to finally have the Corsa Cat Back system installed on my jeep. Due to the fact I installed this at home without a lift I think I have run into a couple issues though. Thought I would post up as I would love some insight on some of this. I'm going to try to explain while keeping this short as possible.
I did it myself in a garage with no lift or anything, so install was a little tricky. I had a huge problem lining up the rear mufflers. Basically the hangers in the back were pushing up into the body rather than hanging down as I tried to fit them into the axle pipes coming from the front. I was able to twist the axle pipes around so it would finally fit together, but still had the issue with the rear muffler hangers pushing up into the body instead of hanging on the rubber mounts.
Then as I would try to even the rear mufflers out, they would detach from the axle pipes even though they had been snugged up just enough to adjust. Finally I took a break, came back later, loosed everything up, twisted the axle pipes a little more and got it to where things were staying together but not hanging right, (the hangers still pushing up into the body and very close to the rear bumper).
I decided to fire it up and see what she sounded like, as it seemed everything was together. On two spots I noticed water dripping out of the connection spots where the pipes are clamped together. I made sure to torque everything down to the specs in the instructions. When I took it for a test drive I noticed some "Farting" when shifting to 2nd and then 3rd gear. It is much worse when at WOT.
Took it to a muffler shop and asked them to adjust the whole thing on a lift as I did not have one. Did my best to find a good muffler shop but..... looks like they may have just bent the hangers or something in the back to get the pipes coming out even and keep the hangers from hitting the body. Needless to say I still get the farting when hitting the gas moderately heavy, and now when I sit at lights it feels like the whole system is vibrating, causing this super deep bass in the cabin....... no fun at all
Any input as what could be going on with the "farting" and the vibration bass would be greatly appreciated. Thanks for reading.
