The Clifford long tube truck headers are the best exhaust choice available (also the most expensive), otherwise the Langdon cast headers are no slouch. A budget performance option is the 292 cid HD exhaust manifold with 2.5" outlet is also an option and available from T.H.E. Company:

I have a car so the Clifford headers are not an option, the hang way too low. And I'm on an extreme budget so I'll be going with the 292EM.

With the stock intake and a Monojet, you might want to look into replacing the factory 210cfm Monojet with the HD 250cfm Monojet from a 292 truck motor.
