Utopia it would be interesting to know what Silmotor system you have as my headers which have the cross over pipes are only around 45mm from memory but are very light compared to the stock pipes. I've got some unbranded 2/3 length oval carbon cans for my bike so the system is much lighter than original and potentially will be quite loud. My purchasing was led totally by the look I wanted to maintain with a secondary nod to sound and performance.
