i have a 1990 305 tbi, i have stock manifolds and stock everything else. im putting in one of those new magnaflow catback 3 in systems, and i ordered the ceramic coated hooker 2460s and the y pipe that goes with it. will all that stuff hook up together no problem, or what. and does the y pipe take the place of my stock cat? or should i replace that as well. and if so any suggustions on one that would work with the other stuff im putting on.
any info would help
thanks
