I want to put cat back exhaust on my 92 sc. I was thinking about doing a 3" full system (pipes, hi-flow cat, everything) Would 3" be to big or should i do more like 2 1/4 or 2 2/5 or any suggestions would help. I was also wondering should i end it with flow masters or something else. One last thing should i go with a single pipe cat or one that is one pipe incoming that spits into two outgoing?

3" is to big my friend has a 99sc2 and has 2 1/4 and a cheap tin can and it sounds so good so do 2 1/4 with flow masters
