Nah not yet, coming this Monday or Tuesday I'll be ordering the cat back exhaust then I'll bolt everything on at once. For some reason I just like doing it that way better than peice at a time. I'll let ya guys know when I do though. I never got a 1/4 time in stock form (plus intake) but I got an 1/8 of 9.5 @ 76 so I'll have a little something to compare when I bolt on the header and exhaust components.
