Cheers for the info mate, I think I'll give them a shout regarding a non valved system then

I've just got back from them. They're taking the Dev exhaust off and fitting a final design one. Pick it up next week. This is for my b8. So I'd guess they'd have the system for sale soon.

Exciting stuff Shinobi! Make sure you post a vid on here of the final system.
You guys contemplating an unvalved version; if it's as loud as a valved system with valves open, you'll have to be brave!
I was at a mates house yesterday for a birthday party, took him for a spin and as we were pulling up about 100m from his flat, a street over, he asked me to give it one "proper anti social rev." We walked into the party with a couple of people debating whether that was a superbike or lambo they'd just heard! Nope, just my sensible family estate...
