what are they made of? is it stainless steel or titanium?

standard R1 carbon can

cheers

My carbon (covered) one is steel. I think that the titanium ones look like all metal

I never knew they were carbon til mine arrived
so the exhaust pipe is stainless steel you think? sounds good to me! makes things easier!

cheers

I think they were SS up to about 2003 and then titanium. Someone will correct me.
