I have a 2017 CVO Limited and I would like to add new slip on mufflers for a little louder, deeper sound. I'm not looking for any horsepower gains or anything crazy.  My question is will I need to tune the ECM to match, and will installing them void the factory warranty??

That's a great question! I know the rule of thumb has always been you can do either a breather or exhaust without. The CVO already has an air cleaner but my guess is that since the bike is tuned for it, that the same rule stands.

I'll be watching this post.

You would see & feel a significant change with a proper tune on your bone stock bike... economically, install a set of FullSac CVO cores & tune with TTS & you'll be a happy biker
IMO the aftermarket muffler companies are getting out of reach with what you have to pay for them these days.

Thanks Mr D, however I have an opportunity to get a set of new mufflers as a promo because they want to put my bike on their calendar/website for advertisement.  I'm hoping to get them done before Daytona in March.  I can't release the make yet but they will definitely be the first of their kind on the market that I know of...I'll post pictures if it works out.

Even more reason to get the bike properly retuned for the new airflow change created by the slipons.
There is no shortcut to get around recalibrating a bike for its own ideosycracies and production variances.
While I can name more than a few dissadvantages to riding a modded, untuned bike, there is no disadvantage to getting your bike dyno tuned/recalibrated for best mileage, power, smoothness, response, and decel backfiring.
Dyno tuners are your friends and can make your bike run better than any untuned (canned map) bike with the same mod(s).

I too am looking for something to get more sound out of a 17'. If you do this, Please post a sound clip so others can hear.

So I've been informed by the dealership that just adding slip on mufflers don't void the warranty and do not require a tune of the ECM.  They even install them on new bikes for customers before they leave the shop, without a tune.

Thanks for all the input above...much appreciated! I'll post pics soon:2vrolijk_21:

I'd flip the tips over for a "Downward Slash" if it were me...    Just my preference.   They look like they are upside down

and i'm just the opposite.  i like my exhaust tips to follow the slant of the saddlebags...

X2... agree w/you... if they are going to be slant tip exhaust I also think they look better flowing w/the lines of the saddlebags.
