Recently we added a new item to the webshop. After a lot of testing on various tracks with Stefan Wijers / Han van Hal we can now also offer a Bull expansion pipe for the Zabel / VMC together with the Oval silencer we have put a bigger performance to work. At Gp level it is already being driven with but also team van de Lagemaat will soon have it available so that we get even more input. Bull Exhausts is known for that it also continuously develops during the season.
