I've seen both set-ups and it's hard to tell the difference,but I haven't seen a back to back dyno comparison. I'm runningREVO II, CAIwith a 100 cell 3" DP into a 2 3/4" CATBack, and my car is screaming loud, and damn fast. Go with the best sound at a reasonable price and you'll be fine.



Cheers!
