i sprayed the bolt every night for a week. so not at all. but the CAT has the stupid threads in it. so i had to drill those out cause they were just rotten away pretty much. I didn't mind doing that though. i dont get why infiniti made it with threads on the CAT. so yeah that's really the only "trouble" i ran into. and getting those damn exhaust hanger off. haha.Looks good. Keep an eye on your bumper that it doesn't start melting. The maui needs a new exhaust. I'm scared to try and undo any of the bolts. They all look rusted really bad. You have any issues?
