This particular problem is the whole beauty of the MAC catback system most people in here say is crap. How easy would this have made the job?
I can tell you- when I hung my 3.5" kit in my Cobra bumper, it was a breaze. The two peice tailpipe makes getting it strait a snap- until I added the panhard that is, and was too lazy to snake it through so I just cut the tails off entirely with a sawzall.
Unfortunately, this is better of the only two pics I have left of the car with tips, it isn't strait on the back so you can't see that they were lined up well at all and the shadows underneath make them look off- but they did come strait out the back perfectly even. We even put longer hangers on the back so we could have them point towards the ground slightly, and it worked. There is no catback on the market as accomodating as MAC. I don't know why they don't all come with two peice tails.
