just ordered borla cat back from pickuptruck.com, got it for $480.00 shipped. this guy steve set me up. catted x pipe, gears, cat back should all be here this week. going on 2/25 to get gears and x pipe installed. might just have them put cat back on since they will have it apart. installed volant cai, the other night. have not driven car yet, so who knows. does not sound that much diff. cant wait to get this s*it done. they told me $250 to $300 to install gears, $50 to $75 for x pipe, shouldnt be that much more for cat back if i decide to throw that in. larocco's in n.j. is doing the work. wish me luck.
