I have a vid on youtube with my exhaust. I have 2 Flowmaster Super 44's on my Alero. The vid goes thru different RPM's. My Youtube name is Redogonyx. Just search that. Youtube doesn't work on some of the company computers
If you have stock exhaust and don't plan on upgrading the entire system, 2.25 inch is the stock size, if you are going to upgrade, do a 2.5 inch catback. Actually on the Alero, rear O2 sensor back
