I bet with a sick tune you can get 20HP from the primary deletes and it is bolt on with no cutting. If you do decide to go Supercharger or cam then you will need headers.

You dont "need" headers with a supercharger. Jenetty racing installed a Maggie setup on a stock exhaust 6 gen and its making 600whp. Would adding headers increase gains sure, but its not required.
