Twin Loop

I was wondering what the performance benefits of a twin loop style muffler are? I just received my new header and have a 2 1/4" exhaust system that connects to a pass through muffler. I didn't know if I would benefit by putting on a twin loop muffler.

Unfortunetly I am not sure. Cst Fuzz may have some insight on this. Otherwise I would suggest going to sixsphere.com as members there are very knowledgeable in the performance aspect of the s-series.
