Hate to give yamaha 25 bucks a piece for the same old donuts that they run,i remember a few years ago someone on here was making some up of better material,was it brass? Does anyone have a list of that donut and price,and contact to buy them?
 
Doing my 2 Attaks now at the same time as I type... with the Copper donuts..
 
Good to hear,are you following rockerdans write up?
 
This is the 3rd time I've had to do it so I'm running on memory. Probably his way that I learned on.
I'm not sure if they said to change the gaskets inside the Y pips or not but I bought new ones anyway.
My improvements over Dan's is Copper of course and I got some Grade 8 deep allen head bolts to replace the shallow ones OEM. Got them at a hardware store. They are the ones attaching the Y pipes to the tunnel. They will be easier to take out next time because they are grade 8 and have a deep allen hex socket.
Finished the first one today and will put together the second one tomorrow since all the parts came in I need.
