Who makes headers for my '89 and how much? I heard Camaro headers will work.

Camaro headers WILL NOT work, due to the Caprice's frame.

I am going to get some Hedman Hedders from Summit for like $140 IIRC. They really aren't the best, but are good enough for my needs (350 crate motor and TPI induction). THE BEST is Tri-Y headers, but excpect to pay an arm and leg for them.

The NAISSO store is the best place I know of for exhaust parts (and everything else for that matter) for the Caprices/Impalas. However, this won't help you out to much for headers because all the headers on that site are D-shaped for the LT1 9C1s.
