I tried to search the forums and could not find a definitive answer.

Will replacing the stock cat/muffler with a Competition Werkes slip-on exhaust void the Manufacturer Warranty on a pretty new (only 350 odo miles) 2025 R3 Storm GT?

This machine is great, just too quiet for me and these NJ roads (drivers).

Thank you, I appreciate the assistance.
 
It will probably affect the fueling and it might require a remap to prevent running over lean. As to the warranty, this what I found in my Owner's Handbook:
The motorcycle’s exhaust silencers are warranted for 12 (twelve) months from the commencement of the general motorcycle warranty. During this 12 (twelve) month warranty period, internal corrosion or deformation of internal baffles are excluded from the warranty. After this 12 (twelve) month period, the motorcycle silencers are excluded from the terms of this warranty.

I take that to mean that the silencers can be replaced without affecting the warranty on the rest of the bike.
 
I took my '25 GT for the first service to a dealer with a Werkes exhaust, no one said anything.
A1A Rider, are you in the US? My black Werkes exhaust just came in today (with Black db silencers) and I want to swap it asap. I was just worried about bringing it in for my first service appointment in 2 weeks.
 
Great info! Thank you!
 
I disagree unless the Rocket is somehow an exception. Normally slip ons provide minimal performance gains, they certainly don’t affect fueling or require a remap, and mainly are just for different aesthetics and sound. That’s usually why they never void warranties because it has minimal effect on a bike other than reducing the weight somewhat.
 
I agree with you. What I mentioned as great info was paragraph 2 and 3. Especially the fact that it shouldn't affect the warranty.
