Question regarding the set up i have now. I currently have GT Cat-Backs on it. I want to take off the current gt catback mufflers and replace them with the 2 40s i got now. The Tips and the inlet ends that connect to the muffler itself wont have a problem in size right?

 

If you take it to a shop, they should be able weld an adapter or just get a nice bead around it if one is 2.25" and the other is 2.5" - that's what i had done-2.5" midpipe, to 2.25" pipes to 2.5" muffler, to 2.25" pipes to 2.5" tips (inlet).... kinda whack but I decided at the last minuteI wanted 2.25" piping since i have no cats.If they can weld good, you shouldn't have a problem.

 

Ight cool, yea i shouldnt have a problem then. The guy i go to does really nice work for nice deals.
