heres the deal still have the factory exhaust system from when i had a 305 in my car and I know that it is even more restrictive then what a 350 should normally have, so I was wondering what I need to upgrade as well as go with performance exhaust? ect...headers,duals, or whatever give me some opinions

For comparison the differences start right in the manifolds (In the exits), the Y-pipe is smaller where it enters the cat, and your going to change the cat-back anyway.....

Start from scratch.

 

okay give me some more options, what do others like ive heard alot of borla but it is expensive?

Yes borla is very expensive, but it is stainless steel so it won't rust and will last forever. SLP headers I believe are stainless steel also, but are also somewhat expensive. Most people love them. If you need to follow emissions get a good high flow cat and a nice 3" catback such as edelbrock, hooker, flowmaster, etc. Oh yeah and I wouldn't go with duals either, unless you really want to be spending some money and most likely have ground clearance problems, unless you have a really good muffler shop there.
