it's an '07 for sure. The '06 800's were not running an O2 loop. There's plenty of O2 sensor bungs available on the interweb, but they're really no more than you've prepared for with an appropriate size nut. I've got to believe that any competent muffler shop can handle it in no time. Just be sure to mark the pipes so that you don't come home to find you've got a placement / clearance issue AND a freshly threaded hole in your header.

rossa'ruck!

Yeah I had to send the pipes back. They were actually too short between the header and mid pipes. Pretty pissed off about the whole situation

Aaahhh.. I know what it's like to be close to starting a project but having to pull the plug. Better all around to do it all with the right parts and no improvising.

I've heard the Arrows pipe set on the S2r 800 & 1000, and it's definitely "the doggy's bollocks."

I went with a Leo Vince pipe and kept the udder since its throaty but still neighborhood friendly..
