Default Efficient C6 Exhaust Systems

What's the most efficient exhaust system for the C6?

I'm not looking for *best sound* but the most effective, high air-flow commercial package to augment my 1 3/4" headers.

I've been using dynamax exhaust, but am looking to get even better evacuation.

If you recommend an exhaust system, pleas state why you think it is more efficient - thanks.

From my understanding, the factory mufflers are not all that restrictive.

Dynomax Ultraflow mufflers are just about some of the best flowing mufflers out there. So would anything else that is a straight through type of design (i.e. certain Magnaflows). Stay away from Flowmaster if you are looking for flow.

He needs a very efficient cat back to make up for crazy restrictive headers.

I used to think so and when I installed them that was the common consensus, however evacuation tests show that they are below what I think a good system could be, so I'm asking for alternative recommendations.
