I've got a 2.5" HKS cat-back, and I'm in the process of buying a downpipe. More than likely I'll be picking up one of the ones off ebay. My question is, should I get one of the ones that is a 2.5" all the way (that necks down to 2.25 where the cat would be) or one that becomes 3" after the flex coupler and then necks down in the same spot?
Would having the 3" be better even if it's only that little bit there, or would the 2.5" one be more suitable (even though both neck down to 2.25").
