Does anyone know much about the Leo Vince full exhaust system that's available for the FZ6R. I was at a local bike shop in Vancouver Canada and was inquiring about the Two Brothers exhaust system when the fellow at the bike shop showed me a Leo Vince exhaust system made specifically for the FZ6R. The photo of the exhaust is actually the Yamaha xj6 which is the naked version of the Fz6r which is sold in Europe. It's pretty much the identical bike in a naked version. The exhaust photo can be seen on the Leo Vince USA site so it must fit. Anyways i think the exhaust is awesome looking and i am wondering if anyone purchased this exhaust in North America. I also can't seem to find a sound clip of the exhaust.Leo Vince exhaust systems are produced in Europe (Italy ) and are of a very high quality.The opinion from the bike shop was that the Leo Vince system is of a much better quality than the 2 Brothers. Please let me know if you have any info. Also is it true that because of the design of the Fz6r exhaust system that only a full system will work. A slip on muffler will not work. Cheers and thanks for any advice in advance. cheers.
