Hey everyone. What are the cons of having no y pipe bolted to the stock manifolds?? Will I blow out the valves? Seems like I have to run it this way until I can get the new manifolds to start my turbo build, because the bolts in the manifold-y pipe flange are broke and stuck... machine shop wants $30/bolt to remove them. We just dropped the new engine & the manifolds left on them in the car tonight. What should I do?

Are you talking about having no exhaust past the stock cats? Or the stock manifolds?

you cant run the car with JUST the stock manifolds....you have to have front o2s

Good God man! That would be loud! But you need a place for your o2's so it looks like you'll be shelling out the $30 a bolt

um, if youre talking about nothing from past the cats you should be okay. if you dont even have cats on, then damn I dont know. ive heard you can burn a valve that way and also that would just be even more loud and obnoxious than just no exhaust. I ran it just manifolds and cats for a while until I got headers and it just sounds like an old truck untill you get on it.
