Yes, thank you, we all know.
Any of us that have been researching pipes and know how to use the search function have read that thread.
I read that and many more Hawk positives before I made a purchase. I'm sorry for your bad luck but they certainly aren't all bad. Just like the thread I came across expressing an issue with a broken D&D mount doesn't mean that everyone will have the same problem.
Honestly, if it breaks eventually the small cash I spent on it was already worth it for the miles I've turned and the opportunity to try something different. It was a nice little upgrade compared to the quiet, farty stock can. And at much less the cost of a new D&D. Also, at the time my research yielded that a D&D wasn't the best choice for the xb9. They are different animals to the xb12 as we know. My pocketbook also agreed that I'd get as much satisfaction from a less expensive alternative.
So what-
This still isn't an exhaust thread. If we can't help answer the original question we don't really need to be here adding.
A pipe choice has already been made - topic over. Now onto a tune.
