When I started building my 85 I bought new stock exhaust manifolds not thinking about duel exhausts. I am wondering if it would be ok to install duel pipes and mufflers using the stock manifolds or is it necessary to use headers.
I have not built up the engine, it is a stock 350 sb crate motor. I am wanting the duels to give a little bit more hp.
Any imput on this?
