Looks like no has got to you for a while. I am doing research on this and this is what I came across. A company located in India. Barrel Exhaust. Here is a link for the website. You would need a 63mm. I measured my exhaust tip last night with a caliper. As of right now they are sold out of the 63mm. Were you able to find anything else?
