Just got done doing the APR Sport Turbo-Back install. Took only 2 hours and wasn't tough at all. The only snag we ran into was the front upper bolt on the downpipe flange. Well.... also didnt have the band clamps that were supposed to come with the system, so good ol' Home Depot special hit the spot, 3 for $6
The APR clamps and gasket are coming in soon, so when I swap them in, I might be able to take pictures and do a thorough write up on the install. However, I would like to know if ppl are interested in it. I would hate to go through it all and no one read it :'(
Overall, the system sounds great. I was looking for a STi / Evo sound with exhaust. Basically, a deep, throaty exhaust note with a high pitched whirling sound of a turbo in the background as you pull away. Still burning in the high flow cats, so the exhaust note is only getting deeper. I would say it's definitely worth the money. Oh yea, UPS lost the gasket and clamps. APR had nothing to do with it.
