I’m a new owner of a 701 Vitpilen in Australia and I’m also considering my best exhaust options. Weight saving is key on my mind – that’s a huge drop in weight you have achieved over the stock cat/exhaust. Zwillis, how much does the stock exhaust alone weigh? Is the cat the heaviest part of the system?
