Looking to get a full exhaust for my 2017 YFZ450R SE but not sure which direction to go. I’m leaning towards Yoshimura as it seems consensus is that they offer solid quality, performance, and are loud without being too loud. However there seems to be a lot of hype around HMF. Any thoughts? Open to feedback on other manufacturers as well.

Thanks!

Yoshi rs2 all the way i love it sounds sick and gave me plenty of power all through the rpms also comes with a spark arrestor and fits great

I appreciate the feedback, I also like the look of the Yoshi as well

HMF is way TOO LONG. YOSHI FTW.

I would definitely go Yoshi over HMF. I have seen one or two HMF mufflers that just didn't hold up.

I have a stock 2019 YFZ 450R SE and thinking about putting on a Yoshimura full system. If I add it to the bike do I need to do anything else as for as the mapping or anything like that or am I good just putting it on?

Thanks.

You will need some sort of programmer that adds fuel (PC6,Dobeck, etc); however, I'd suggest an ECU swap and go with a Vortex it's totally worth the extra expense.
