Hi Bikeracer.
I'm toying with the idea of a pipe, but 2 days into ownership in crap weather I'm not sure of it's worth it at this time. Come the sun I'll have a different mindset. I was explaining to a Porsche owning mate about mods and he didn't get it, explained it's like owning a bike, never quite good enough.
Why are you going back to a stock pipe? PM a price and I'll mull it over.
