my new to me quad was just installed, and I'm curious about the OAK. I've read that some need to be piped in through the back and into a plate on the floor. Mine has a black pipe running from the pot to the outside, under the exhaust. Obviously I would just connect the venting to that pipe. Is there a cheap flex pipe to use? I think the pipe is 2", but the smallest I can find is 3". I know the quad kit has a 2" pipe but it's over $100. Any ideas?
