yes the AA exhaust is "suppose" to be a cataylist back exhuast, but i've noticed that it doesn't go all the way there. You know how there is a good amount of piping after the cataylist before it goes into the muffler. Well the AA's pipes goes only halfway to the cataylist so i guess it's like a "half" catback exhaust??
Anyways I didn't try out it's top end yet, so i dunno about it's power gains, but I reckon that it can only be felt by a dynometer. But it does sound good though, isn't that all that matters?
and yea, thanks daytona, i'll try to watch out more often!
