Just fitted a MM 2 in 1 exhaust to my girlfriend's 07 xtr. Looks great and certainly is a practical improvement over the stock ones.

I have got one issue I'm struggling with at the moment. I bought the exhaust on ebay from someone selling their XT but their bike must have been a couple of years older as the older MM pipes don't have a place for the Lambda sensor which the stock ones on '07 bikes do.

My question, and one that my local Yamaha dealer and Paul from MM were unable to answer is what do i do with the Lambda sensor? Will the bike run with it like this or do i need to do something?

Your expertise and thoughts would be much appreciated...
