I am getting a new exhaust on my car and I need opinions. Should I get a y-pipe with both headers going to it or should I run duel exhaust all the way to the back? Is there a difference power wise? Will a pipe on the drivers side scrape? Any comments will be helpful.

 

Depends on emissions where you live. There might be minor ground clearance problems with duals, but I think No4NJunk doesn't have any problems with his. Duals will flow a little better than a y-pipe design. If you're just looking to free up some HP and not really interested in making a high HP motor, then a cat-back would be fine, but if you're looking to squeeze out every last bit of HP duals would be the way to go.
