Would?

On my 2000 Pontiac Sunfire 2.2L would it make a difference in power delivery if i changed my stock single exhaust duel tip to a single tip? Curious because i know it could decrease backflow!

if you increased the pipe size it would more than likely up the flow...but if you didnt increase the size it would probably restrict more. if i had that set up id get that splitter muffler cut and a y-pipe welded in then have small dual mufflers mounted plus increase pipe size from the cat to the y to about 2.5" and the same for both sides after the y. then it would sound evil and look evil... :evillol:
