I have a 2018 Ultra Limted and looking to upgrade the exhaust as the stock are too quiet and looking to upgrade but the way Harley has their warranty would like to find a set of slip ons that are compliant. I am looking at the Cobra Neighbor Haters. Waiting for a response back from Cobra now.

 

What has your dealer said? Technically if you're not removing your cats or tuning with a tuner that takes your bike out of EPA compliance, then most slip ons are fine.

 

So far, I have only seen actual EPA Certifications published by S&S...no other aftermarket slip-on manufacturer that I am aware of is willing to commit anything to writing.

 

Fuel moto has these. I thought the outlaws were also tested, but it doesn't say on their page.

EPA is noise as well not just pollution.

Vance and Hines Eliminator 400's and High Output's are EPA compliant. The certification is on their site.

 

 

RCx mufflers are fine

 

lol trust me. You'll have no trouble meeting EPA noise guidelines on an M8 bike, regardless of exhaust.

 

you missed the point, if they are not tested they are not compliant therefore it doesnt meet the original posters intent.

 

And you missed my point. Noise or emissions, The majority of slip ons FOR the M8 are EPA compliant. As far as I know, there hasn't been any voided warranty over JUST slip ons. Only when you remove the catalytic converter and/or tune with a tuner that takes the bike our of emissions compliance, do you risk voiding your warranty. With the M8's I doubt the noise ordinance would ever factor into it. Unless of course you live in California and use a straw to drink sodas. lol
