2015 Sound

[bigbird]

My my, you are a chippy little dude, aren't you. I have driven on a 15 - you haven't. Until you ride a 15, a listen for yourself, you really have nothing to base your opinion on......follow?

No need to jump on me.
Nobody here is commenting on the sound of the mufflers, only the reason for the different sound.
Limoles thinks its due only to the different external plating, and he emphatically states the 13/14 mufflers are identical in construction to the '15 except for the external plating. How does he know that all three model years have the identical mufflers without seeing engineering drawings or cutting them open?
Nowhere did he or I comment on the sound, so my driving a '15 is irrelevant here.

For those who can understand the Laws of Noise Pollution/Noise Control there are State/Federal Laws which regulate the amount of exhaust noise/note emitted by motorcycles, autos, light/heavy duty trucks and buses. The norm is usually in a range of 84/92 Decibels and is measured at variable feet distances from the source. Most Safety Inspection Stations, some Police Department and all Heavy Manufacturing Facilities have Decibel Meters which require "Certification" to assure their accuracy as their results can usually dictate the need for "Personal Hearing Protection". That said, the current argument over which year F6B has the louder/throatier stock exhaust note is easily settled. A side by test of 2013,2014 and 2015 using a Calibrated Decibel Meter will provide "proof positive" which exhaust emits the loudest note. To my knowledge all stock motorcycle mufflers carry a "embossed/engraved" Federal Warning" about modifications which would tamper/void the Factory Designed/Regulated Noise Level.

Don't kill each other over a issue, in this case "exhaust note", which is easily and accurately answered

Sounds like a matter that could be resolved in September w/a decibel meter, over an adult beverage.

Ya. Hold my beer and watch this.

Enough noisy bikes, that is why I'm extremely happy with my 2015 Deluxe with the 2014 chrome pipes on it. Quiet, nice, I can listen to the stereo and not be bludgeoned by noisy exhaust tone. Suits me just fine!003.jpg

My stock M109 was twice as loud at idle than this 2015. I find it just right when alone. Can hardly hear it when riding with my 9'er friends. I've never been along side an earlier model to compare. I'm sure others here have and can give a true comparison. On it's own, it's pretty darn quiet, even with this newer "loud" version.

+1 on what dog said. I recently installed a like new set of 2013 mufflers (including shields & tips) on my 2015 - wow, what a difference - music to my ears at last! Much quieter and no more annoying resonance and drone while accelerating in the 2K-3K range! Completely gone. I'll never go back to the 15 mufflers (and no, they're not for sale).

Like some others, I own both sets and have examined both, and yes, they are different in a few ways. Those who have said they're the same haven't done their homework. Take a look at the pics below. The exit pipe on the 13/14 muffler is short and slant cut as well as being below center on the end of the can whereas the exit pipe is centered on the end can for 2015 as well as being a different configuration. Tips are also vastly different (sorry I didn't have a pic of the 13 tip). As for the other end, when looking down the inlet with a flashlight, the 2013's have a baffle about 1/2 to 2/3 of the way to the end, whereas the 2015's baffle is 6" to 8" closer to the inlet. Don't know what prompted mother Honda to make these changes but suffice it to say that I am much happier with the 13s, it's not even a close call. Don't mean to start another controversy, just saying . . .

When i first got my 15' i thought the sound was from the engine as it was louder than expected, kinda like i supposed a Porsche flat 6 would be but i know i loved it. Over time i now realize its the pipes, absolutely perfect for me, mind you as a veteran i have hearing loss and so i could imagine some may find it a little, or a lot, too loud.

My point being and its been made many times before, every rider has different preferences. This 'sound' is mine.

I LOVE THIS BIKE!!!

I have a 2015, with 1600 miles on. I first noticed the sound to be a little annoying at about 65 or 70. Kind of loud coming thru my arai full face helmet. It could be my helmet.

I guess I am getting used to it. It does not bother me any more.

My friend has a 2104 Valkarie, it has the same sound at idle.

For entry level models at approximately $20.00 you can put this issue to rest at this years Rally!
