I am currently running 15x10 (with 6.5" backspacing but I am using 1/4" spacer) Weld draglites with 275-50-15 nitto drag radials. I really wanted to go back to tailpipes and quiet my car down a little. If I went with the Mac 2.5" catback kit (bolt on tailpipes) would I have any fitment or rubbing problems?
