i actually just installed the skunk2 catback on my car today after work, replacing my very much past blown out magnaflow catback that has been on it for 10 years....lol

i actually have a dc shorty header and a ebay oem cat replacement. and it lines up for me but the ebay cat flange is too small for it and it has a 1/8 smal gap in the bottom just because how big the pipe is on the skunk2.

i was going to post on here to see if anyone had had similar issues like. i guess maybe an exhaust shop could fix that until i can get the skunk2 header
