Eisenmann Full Cat-back VS Akra Evo

So I'm looking to purchase either one - anybody have any thoughts on which one performs/sounds the best? The Akra is relatively more expensive but I like the wireless valve system.

I think people will notice similar performance gains from each exhaust from a numbers standpoint. If money was no object, between the two I would choose the akra evo. I like the wireless valve system too, and the titanium exhaust should be lighter than a stainless piece, so a little performance (who knows if you can actually notice it). Probably can't go wrong with either.

10k for the akra evo with wireless valve would be tough for me to swallow. Thankfully I am more than satisfied with the stock exhaust note. I might add a downpipe at some point for a little more volume and more turbo noise.
