Headers for 69 big block camaro

[mbuckner3917]

Anyone have recomendations or thoughts about headers for a 69 big block camaro?

2" with 3 1/2" collector. I want non-coated so that they can be ran on the dyno and then coated.

Debating between Hooker and Doug's

I'm also leaning toward the 3" rear exit x-pipe system from pypes performance.

The car is a convertible how much does the bracing in the undercarriage affect the exhaust system?

Thanks in advance
