Just got finished bolting on my APS turbo-back, I've gotta say I could not be any happier with the results. There is a definate improvement on the butt-dyno and the sound is just WOW. but I have a question for all my fellow APS users am I the only one that had to grind off some of the divider that seperates the exhaust and the wastegate exhaust section, It was probably about 1/8 of an inch too long. If I didn't have a grinder handy there would have been no way I coulda got it on.
EDIT: APS sent me an E-mail and explained to me why I had to trim a small amount off the divider, I'm very glad I chose APS most companies probably wouldn't even have cared let alone sent me an E-mail to explain. BIG thumbs up from me for APS.
