I know. There are a few guys on
www.fullsizechevy.com that know tuning and exhaust inside and out.
I went with a Flowmaster 50 single in, dual out with the factory diameter tails. They dump similar to a Buick GN style.
I still run the antiquated Hypertech Power Programmer III (HPP3). When I bought it, the custom tunes were no where as cheap as they are today.
