it is very very simple....the throttle butterfly flaps are the only reason why the R8 V10 has let Power then the LP560
The Flaps start closing down to ca 80% above 6700rpm.....so it is only a way of air restiction......plug in a laptop.....change the flaps position and done........
The Exhaust is the.......1:1 copy of the LMS V10 GT3.....as we had acess to the original pipes.
The only different , not more CAT and NO Silencer at all, and it is a 5 in one setup multiplied by 2 makes 10 cylinders, it will be very loud , at only problem why it is not on the car yet, i have been on the road like hell.
There are probably big fines in many U.S. cities for removing the Cat. Are the power gains big? If so buy or rent a place in the boonies to avoid any testing...BUT you may still get busted while traveling a broad. Where is Bodhii the guy who despises "Seat of the pants" type dynos !!!!!!!!!!!!!
