Setup question
Setup question I have a 220/220 .581/.581 115 lsa comp cam with some unported ls6 heads going into my 2000 camaro z28 A4,i also have some long tube headers but im debating if im going to put them on or not due to california smog 
,do you guys know what kind of numbers my car would put down WITH stock manifolds and a catback compared to longtubes and a ory? also would i touch 12's with both?

i thought that they made longtubes and catted y pipes that were legal in cali? do what you have to do not to get a ticket or anything. but imagine you running two miles with only a straw to breath through. thats what your car would be like without longtubes and a bigger y pipe. i dont know how well of a comparison this is. but with just bolt-ons and crap kumo's i hit a 12.6.
