Hello all . I have a vibrant header and downpipe with the cat-deleted and I am wondering if anyone knows the size of pipe off thier heads? I want to buy a magnaflow high flow cat and throw in there to quiet my car down , just wondering is it 2.5 inch pipe to make sure I order the correct cat size so it can be cut and welded in place.
Thank you for any input !

 

2.5 " is correct
