As I understand, (from the service mgr at my dealership) you can change either the exhaust or the air intake without a tune. If you're changing both, a tune is required.
I wasn't crazy about the look of the stock mufflers on my 2020 RGL either. Look for a set of CVO "take-off" mufflers. That's what I have ended up with.
Similar sound to stock...maybe a bit more "throaty". There's plenty for sale on eBay, etc. (or on the Forum Marketplace here) at very reasonable prices. Think I paid less than $200 for the set and they looked like new.

Basically the same as stock but with a different look that some may like better.
The M8's do not need a tune after upgrading the air cleaner or exhaust.
Unlike the Twin Cam's the M8's do not come from the factory overly lean and do adjust to change a bit on their own.
With that being said, you would see a benefit in getting a tune after getting these upgrades, but it will not harm the bike to not get a tune.
We have a great video that discusses this topic in depth some may find helpful.
Experience has also allowed us to put together a report with some interesting info on M8's.

I just got a new 2024 ultra limited. I am happy with the performance and honestly with the sound too, but I dont really like the looks of the stock mufflers. Has anyone put slip ons on their 2024 ultra limited without changing exhaust or fuel management? I know some people say not to do that, but I am just wanting to know from someone who has actually done it.
