it is just me, or does no-one indicate weather the exhaust they are selling online has an O2 sensor port with it or not. I assume most from the USA wont have one. I wanted to get an arrow exhaust for my 650RL, as it was the only one i could find with an O2 port. I also don't want to pay for the exhaust then pay the same price again for shipping. any one got any ideas? even a diff brand that has the O2 port? any suppliers here in Oz with some decent pricing?
