And I'm making it up at the moment, just working it all out, hopefully in the next few months I'll have a prototype and results to go with it.... I'm talking replacement pipes from and including the snorkel, to the turbos and then to the throttle body. Using the factory mounts and setup for OEM type plumback BOV's or an option to plug up the plumback hole for those who can't get enough of pshhht sounds....
I would use a tig with 50/50 helium/Argon mix, then throw the grinder away as it will make a mess of the pipe, The use of a flapper wheel makes a better job =)
