I have read a few issues with Chinese made copper donuts so I decided that the best thing to do was to go with a known, upstanding vendor so I am ordering them through Travis at Barn of Parts. They are more expensive but I trust his designs and materials so it is worth it to me.

I believe Port and Ulmers are made by the same guy in WI

Of the three BOP, Port, Ulmer - BOP has the cheapest cost for them at $18 for the 34mm if they are all made by the same guy. Who here in WI makes them? If the guy is around the Eau Claire area I would like to see if I could buy from him direct and cut out all of the shipping time/cost.

I have used OEM ones since 07 never had a problem with them.

Not saying they do not work, they just do not last. The copper ones last forever, the OEM has to be swapped out again and again.

I have a local machine shop 20 minutes from me that makes my copper donuts.

 

[Mills]

Huh, I just found several cooper donuts in my spare parts box that I thought I had used up in the past. They are the right size so I am good to go.
Travis, I was able to get a flex pipe from a local guy parting out a Apex via Facebook Marketplace.

I know a copper ones will not wear out, but do the graphite ones provide a better cushion and not be as harsh on the titanium pipes?

 

[Mills]

Had them in my Nytro for 10,000 miles before I sold it and never had a problem with them or the exhaust pipes.

1 set in 14,000 miles WOW!

This is only common on the new style 2011 and up Apex sleds. I have done piles of older units and the stock donuts dont last more then 5 to 6000 miles.
