you want a little backpressure unless you are insane for RPM (not with the 3.3L) 2.5" exhaust is too big for the X unless you are running single exit pipe on the SC or with a turbo. 2.25" is perfect for the NA engine for maintaining torque. I run a 40 series because i like the noise, and the fact that "loud pipes save lives" no jackass in their right mind would pull into your lane if they could hear you coming! if they did i'd just ram them! smile
