I have ordered the Mac Ceramac LT and Dr. Gas X pipe, but I also ordered PI Cams and PI Intake kit from Livernois and Accufab Plenum and TB combo... I think this will really benifit getting long tubes. Without the better breathing on the intake side you wont have that great of gain on the exhaust side. I opted out of getting PI heads because I have a blower going on in the future. right now I'm running a 100 shot of N2O...the bump in compression would be good with N20 but not the Blower. If I were you I would wait to see how my mods do when I get them on. The parts will be in next week and I will have them on the following week. but if your hell bent on LT's Hookers fit, Macs fit, and Flowtech fit... Hookers being the most $ around $750 for the ceramic versions Mac are mid priced $450 for Ceramic and the flow tech are around $300 but I have heard they suck... I have searched all over for a good mid pipe and the Dr. Gas seems to have all that I am looking for.
