I know I;'ve had a few posts about this before rolleyes.gif but yeah i'm finally getting it done, just making sure of some last minute things (big things), I'm getting a 2.5" cat back and I've had the celi checked that it will all fit, but will 2.5" give me less back pressure, enough to give a power loss? i need ideas fast wink.gif

assuming your SX is the 1.8l 7afe, I wouldn't go any bigger than 2.25 inch. backpressure is one issue, but its also completely pointless unless you are going turbo in the near future.

i have a 5S-FE, and I;ve read all the above, just making extra sure, a 2.5" should be okay? but like you were saying, does this mean i would get less low end power?
