88GTStreetRod Member Jan 5, 2004 376 1 18 USA Sep 13, 2004 #1 Sep 13, 2004 #1 I have a 466ci pushing around 550 HP. Currently I have 3 inch MAC Dumps. I am planning on converting this to the 3 inch MAC cat back with tips. I also run 275/40/17 on 17x9 rims. Anyone ever had any issue with clearance or installation problems?
