Either way, impressive results! If you haven't already, look into the ASR intake scoops as well!

Not to burst your bubble, but the Eisenmann muffler won't really provide anything other than the sound. The ASR exhaust eliminates the secondary cats as well as giving higher flowing primary cats.

Maybe the Eisenman engineers literally meant just the piping not the cats. Improving the flow of the cats coming right off the header is a great place to pick up power.
