Is the Apex-I 3" in diameter or is it less ? Because im going to have to get a 3" y-pipe and they say it requires a 3" catback exhaust system, is the Apexi Okay ?

 

I noticed your post about adding a 3" y-pipe. I would personally do a search before spending the money. Dallas and I make a 3" system, but any one who is considering buying one should be aware that one of our customers dyno tested it in Chicago a while back and actually LOST 1 or 2 h/p not gained. This was a supercharged car, the owner was had dynod his car about 50 time in the last few years, so we felt his numbers were accurate. Any way we sent the pipe to another owner who currently has it on and is trying different configurations to see if he can gain power. Wish I could remember his name, if you want to talk to him I would e-mail Dallas, I am sure he can look it up or do a search here, If I remember correctly it was late winter or early spring.Hope this helps
