RB non-resonated mid-pipe vs. RB resonated mid-pipe
 

I am wondering performance wise, what is a better option to do.
1) RB cat-back exhaust with non-resonated mid-pipe.
2) RB cat-back exhaust with resonated mid-pipe

what would i get the best performance out of it?

You want resonated, just the straight pipe sounds like crap.

I could be wrong but I doubt there is a significant performance gain between the two(if any), they are both open and very free flowing since the cat is removed.

Sounds like crap in what way? Is it just too loud?

The non resonated pipe is very raspy compared to the resonated pipe

FYI, you won't get any performance enhancement from either midpipe. I've ran a straight pipe with a catback before. It's fun and loud, but after a couple of weeks I had enough and put the cat back on.

Thanks for all your replies i think im going to go with the resonated mid-pipe.

I had the non resonated one I thought it was gonna be louder. Sounded nice to me.
