Ok I'm wanting to get a 3" catback made at my local shop this week and have a question about what to do about my cat. I know I want to put in a testpipe because Oklahoma has no emissions 
. The deal is right now I have stock downpipe and cat and the pipe is just cut off after the cat. I want to get a 3" catback put in and for now get a testpipe that goes from 3" to the stock size of my downpipe. If I do this will the downpipes that eliminate the cat match up almost perfectly to the catback? Yea it's a newb question but I dont want to have to pay the shop twice to fix up my exhaust when I could have them do it right the first time.
