Kid Racer - On a mild 350 a Y-pipe that's 2.5" from each header merged into a 3" Y is just fine. I would get a nice 3" catback and you should see a nice improvement.

Just get a Y-pipe and catback and you ar good to go.
I don't know anyone who has the TES headers that doesn't like them, or any edelbrock headers. If you don't think the edelbrock shorties will outflow a 1987 chevy log manifold you need to have your head checked out. They weren't a very good manifold. Now if you we're dumping shorties on an LSX engine, now you are pissing away some money. I've installed 3 stes sp far, what needs to be welded? On the dyno they made about 12 more RWH on a 89 TPI, not bad at all for a shorty.
