Evolve E-Tronic Exhaust for BMW E60 M5

We have finished development on our new valvetronic exhaust for the BMW E60 M5. This allows the customer 2 sound levels - street or race - at a touch of a button via a wireless controller. Dyno charts to follow. This will pave the way for further valvetronic exhausts for the BMW range. E92 M3 exhaust is now in development.
