Caterpillar exhaust

Summer time so I have much less time to build my bike, but fortunately there was one guy who made some work for me. A friend from Klub Motocyklistów Politechniki Łódzkiej fabricated for ma a completely new, custom exhaust system - from scratch! His work is just amazing. Below there is a photo taken while he was working on the project. Today I'll try to make a few photos to show You how it looks finished :)
