I'm going to build a stainless steel system for my R80/7 cafe racer and need some advise. The standard chrome system on the bike has a single balance pipe on the downtubes just after the first bend from the cylinders. I've done a bit of research and info that I found says that the balance pipe improves torque and also reduces noise. When I build the system, I'd like to leave out the blance pipe, this is mainly for looks. My questions are 1. would not having the balance pipe make much noticable difference to performance and 2. if it does make a difference, does it matter where the balance pipe is, ie could i position the balance pipe under the sump?
