My tips came in today and I just finished putting them on. I really like the way they look. I installed the exhaust mounts that OP recommended as well. Overall the install wasn't too hard. It took me about 2 hours. The measurements of the tips are 60mm inlet and 80mm outlet. There is just a tiny bit of space in between the tips. The carbon fiber piece makes them a bit thick. Without the carbon fiber there would be a lot more room but I don't think it'd look as good. I'll keep an eye on it of course to how they hold up after a few rides. If anyone is interestested in getting the tips you can contact this
person on ebay. You have to ask him for the measurements as he will have to put a custom order in. They took about 2 weeks to get delivered.
