I know the design, I saw it on a 528 last year in another forum. I personally find that setup to be a bit loud for my personal tastes though I do not doubt it does scare some people at WOT. My personal issue is that I have 2 young children in the back seat and prefer to have a resonator to a muffler setup than stirctly resonator.
G-Power is made by Scorpion so the sound should just be awesome. I can post links to M5's with G-Power exhausts so you guys can get a taste of it...
