Copper Donuts from Pro Parts - any good?

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?

Well that is a good question, my 09 had two titanium pipe failures with them, solved it with stainless Y-pipes from an RX1.

I have seen them broke off before the copper was ever an option.

Yeah those pipes were trash for sure. With copper and RX1 stainless pipes should never have to go back into the exhaust on the 09.
