So whats the deal and what do I need to do if a Lethal Performance catted x-pipe won't line up with my Mac LT headers? It looks like its off 1/2 to 3/4 of an inch when I'm trying to line it up. I purchased the x-pipe used from someone with a good reputation and the LTs were on the car when I purchased them. Anyone got any ideas? I'm really on my last leg of frustration after installing a Cobra IRS myself and now completely swapping the exhaust. I just want to get the car back on the ground again since I haven't driven it since the day I bought it.
