doesnt always mean more power.......if your planning on doing some decent HP built motor,supercharger,turbo etc in the future ide go for the 3 inch.If you just looking for a lil punch and not planning on adding alot go with the 2.5 inch.Your gonna lose back pressure with a big ass exhuast and nothing to push out of it so youll loose some bottom end power
