I wanna do tru dual exhaust, and right now I have a cat less Y pipe into a single in dual out magnaflow. I have a friend who has 2 spin tech mufflers, he said $90 for both. So I'm wondering if this would be a good deal? Any thoughts?

 

I love my spin techs. Pro-streets with my dual exhaust. Sounds awesome above 4k rpm and really not that loud when just cruising.

 

Will I pick up some power by going to tru dual? I've heard that I'm probably out flowing my Y pipe
