Well, I have a change to get a vibrant 3" cat-back. I currently have a zzp shorty header and 3" downpipe with 2.5" exit. Will the vibrant cat-back bolt up to the 2.5" flange or will I need a new downpipe to bolt it up? Pretty sure I'm going to need to get a new downpipe.....just double checking with anyone that has one, thanks!

 

dont need a new dp. just need to go down the muffler shop and have them chop off that 2.5. put a 3" extention in and mount it up. should cost you like 50 bucks

 

excellent idea!!! I don't know why I didn't think of that lol thanks man
