TechArt exhaust, CBP and filters... I bought the CTT w/ those mods already installed. I don't doubt Fabspeed's numbers on the CBP. The filters are probably not responsible for too much power. My biggest issue with this thread (even before you entered the conversation) has been with the IPD claims. I know the IPD works in the 911 world. I own two (one is for sale, BTW). It has been shown over and over. I hope you prove it works on the CTT.

Ok, now I'm really out. Thanks for making your last post more civil. We work toward a common goal whether you realize it or not.
