I've always recommended fab'ing your own (having a local shop do it). If you buy the pipes pre-bent from a shop who's done the measurements before (like i did) then just buy the accompanying muffler and tips you'll spend less money and make more power than side exhaust kits. Look at my exhaust link to see if you like that kind of set up, keep in mind you can still buy rocker panels and different tips if you like the look of the kit's your looking at.
