So I'm waiting in the endless line of getting that delivery update from my dealer for the new outlander XMR 850 2021. I live in Canada and have done some research on exhausts to choose. I heard HMF provides more power but lower built quality. While RJWC provides less power but more build...

Well I had my hmf repacked, and I was checking everything out and it seems that the exhaust is leaking a little air out the back by one of the steel rivets, is this okay? It's not too much air, or should I be concerned?

Shout of to the boys at HMF who cleaned up and repacked my exhaust greatly! Sounds so much better than it did before, and really worth the money I payed, here is a video and some pictures.

I have an HMF slip on exhaust and snorkels was wondering if an HMF optimizer would change anything or is not worth the extra money. And if i got a set of drop in cams would it be best to purchase one?
