Got an 8 inch tip for my truck today. Extremely tight fit. LOL. I didnt like the way it stuck on on a side exit I even cut 9 inches off the flo pro tail pipe and it definately wasnt going to fit dumped. So I got to digging around the garage. Got ahold to the extension pipe for the megacabs. And attached that to the exhaust where it comes over the axle then threw my tip on it. Still a super tight fit. So for anyone wanting a big tip if you dont want to spend an hour adjusting the exhaust ide say go with a 7 inch. But the 8 can be done. I'll post pics and maybe a sound clip comparing tip to no tip if I can figure out how to post it on here Haha.
