1965 Chevy II nova sedan

So ive pulled the straight 6 and replaced it with a 350 and a turbo 350 automatic. Ive got hooker headers blockhuggers and it seems to me that the 3" might be too big? The collectors are maybe 5 inches away from my transmission bracket and it looks as if it (the bracket) might get in the way of my pipes.. Any ideas? What kind of set up are you guys running? ive heard of fenderwell headers but i would like to avoid pulling off the headers and all that.
