I'd say you're right, looking closer it seems it's just an Arrow sticker, the can has a badge with Japanese on it. Better pictures:Drunkn Munky wrote:Its not a standard system, possibly yamamoto but hard to tell from that pic. Not sure on the can but id say thats just a arrow badge on a random can. Does it leak where it slips onto the system? Its usual to have a clamp or springs to secure it to the system.


It leaks from the join to the front headers below, and it may also leak from the join to the back headers, but it does not seem to leak where the can joins the pipe.
By the way, are the gaskets at the rear header flange the same as the ones for the exhaust flanges at the cylinders? I figure I should just replace them all.
