I wanted to try to see how a 2-1 exhaust system would work and would look. I my garage I found some parts lying around and made in some hours a system. And this how it looks like. Not only just for fun but as well as an experiment for our racing Parallel Twin which could be finished this autumn or this winter. Took the bike out today for a test and it really revs a lot easier and sounds great as wel, not too loud and not to quite either.
