Got an extra 426 header for sale?

[Pincushion]

I need one. PM me with details if you have one to sell.

I got what I thought was a stock YZ426 header, but its about a 1/2" too small OD where the silencer meet point is. What Yamaha YZ or WR has 1 1/2" OD at the jnction point.

Not sure if this applies for you, but the original yz400/426 header and silencer hada metalic (lead-like) gasket that was in the female end of the silencer, then slipped over the header. Check out the online oem parts finder for yamaha. It is part #12 in the exhaust section. This should make up the difference in od.

Chech out eBay. Somebody is parting out a 426 and the stock header is listed. I think it was just listed yesterday w/ no reserve.
