Like many others, I can't justify 5 grand on some bent pipe and a pair of cats, no matter how fine the craftsmanship. A more reasonably priced system with good sound and class-leading low back pressure is going to be very popular! I'm getting tired of the WOT hiss of the stock system, which had persisted despite the bypass holes I opened up in the tail pipe.

Can't really add any more accolades than what has already been posted Kevin. Your products are beautiful, beautifully engineered and manufactured, your attention to detail is second to none and it shows in the numbers -- congratulations! I am definitely interested in going with your technology for my car but I have a question. Since I will be moving to back to CA from MI in the near future, I will be back to dealing with annual smog inspections. Can you (or anybody else) tell me if these mods will make it through the CA smog inspection process or would they be a strictly "off road" application? I hope the answer is no problem, cause I would sure like to pull the trigger on your upgrades sometime soon! Thanks in advance for your replies.

Last year, I put an okay time in the book for you guys to shoot for though. I'll look forward to watching another TT best it. If the weather is good for the time trial that should happen as the track was cold and damp last year. Are you doing all three days? Bob

Kevin. My pipe has 1/2 the back pressure of the EP2L. When's the stage 4 crate going to be ready? I want 1 with programming to match my exhaust flow. Need a new clutch too!

Bob, you were smoking last year w/ those muffler bypasses! I'm sure an on track excursion can be arranged this year. 
Doubt I'll beat your time though. Work unfortunately only allows me to be there Sat and Sunday.

Mike: Don't you loose power, especially in the lower rpm range, when you reduce back pressure so much?

I'm not really sure. I would assume you would loose some pre-boost torque. The GT28's do spool up pretty fast though. I'm guessing Kevin's big ZC turbos would spool even sooner (?) The reduced back pressure does enable all turbos to spool sooner.
In reality, who has any noteworthy torque before boost?
