Ok so I’ve been researching a lot about headers, the bolts, y-pipe and cat back. Gonna go with hooker 2462 probably fabricated mandrel bent 2 1/2” y- pipe and a mandrel bent single 3” cat back. Ordering soon... looks like I’ll have trouble with the old and new manifold bolts. By the way it’s a 305 vortec, and I know should just 350 it now but I want something to do.. I hope this sounds ok and up for any suggestions about this topic, R&R, tips about labor and such. Just got it so have tune up and brake ones to do still. Bought al new stainless brake lines. Anyway just thought I’d ask and show myself on this forum. By the way y’all really help and have a lot of good insight and it’s greatky appreciated from my end. Just something to build with my son and pass the time. Thanks for anything and everything y’all can help with.
