Hi everyone, a bit of a different request than usual.

Does anyone know what the quietest aftermarket exhaust is? I want the weight savings but also want it to be quiet at idle. Not fussed about how loud it is at full throttle.

I do a lot of midnight starts and finishes and want to keep things subtle around the neighbourhood.

I wanted the exact same as you , the weight savings, performance, but also quiet low down in the rev range.

I'm not sure it's possible to get all those things in one package. In the end I've ordered the two brothers full system. will report back when it's fitted

if you want quite look for one that is street legal...dosn't have to be US legal but if EU legal is fine.

I have a Scorpion which is EU legal and is fine, good thing is that fueling needs no work kept stock

leo vince evoII eu approved slip on
with two restrictors [inlet and exit of
cannister] while still, loud, under load,
such as overtaking etc, can be quiet
enough at startup/idle, and take off,
so long as you dont over rev her
and ride to the environment..

i would ride away from home downslope,
needing next to no extra revs..
if i chose to take off up the hill
that would generate extra noise..
its down to the rider..

overtakes and off the lights plus
blipping to warn pedestrians etc,
will generate higher noise levels..
but you decide to overtake or not
and how you get off the line etc..

i had my son start her up and take off
while i listened from inside, where
she was less noisy than some cars
and trucks and the stock harley..

'concept' versions of road hondas
often use akr exhausts etc, which become
cat cannisters for general sale..
honda designers/engineers show
their design preferences therby..

its the overweight ungainly cannister
dictated by some regulations
that is the real add-on design..

ultimately whatever the potential,
for noise making, it still comes down
to the rider and her throttle hand..

You will probably find the 2 Bros is loud because it's not EU approved. Most of the big name ones like Yoshi, Akrapovic and 2 Bros are loud.

I have the Yoshimura slip on on my CB300F and it is loud with the decibel reducer and very loud, as in, too loud without. I had an Akrapovic on my Vstrom 650 and it was perfect. I could drive around using low revs with stealth and managed a healthy bark at full throttle. Not sure how that muffler sounds on the Honda.

I think the Scorpion slip on has two decibal reducers so it may offer three levels of sound and performance. Just a thought.

yes, three possible tunes. I use both DB reducers and sounds great, nice and throaty with just the right loudness but never annoying even at top rev.

 

[Wilbur]

I have an Akrapovic and that might be OK for what you want. Its only noisy over about 6k.

 

[Treve82]

Thanks everyone, really helpful.

Danmoto with their carbon GP is the quietest, but still freakin loud even with a dB killer in.
I would presume you'd have to look in the 300-500 range.
If you have a mid pipe, some cheaper $80 slipons come with silencer. The bigger the can, the quieter they are (usually).

I was thinking about going with Akra but haven't seem much information on it. Are you using it with the baffle? Based on the one review I've seen, the person states that power delivery seems scattered about the RPMs -- have you experienced this? Also, does it work fine without a fuel controller?

 

[AlVal]

Yeah, I pretty much ended up accepting the performance vs noise compromise

 

[scubidu]

Would it be just as loud with ear plugs on?

Now how can it be the quietest one but still freaking loud? Just cause you have one? Only one you ever heard?

Scorpion is pretty quiet if not the quietest. At speeds above 60mph wind noise will drown out exahaust noise.

 

[MeeLee]

I meant to say, it's the quietest of their set of 3 exhausts that they make.

 

[Treve82]

Really, i would have thought the Jisu would be quieter than the GP

 

[MeeLee]

Might be.
In the USA they're not available for the 300.
Only the metal can, and some sort of dual horn (aka loud) pipe.

 

[DaBinChe]

Come to think of it, I wouldn't call the scorpion loud but louder then stock....loud is relative.

Fully agree about the Scorpion. It is louder than a stock, but far from being obnoxious. For me it starts to drone out at 45 mph.

Did you ever settle on a particular can then. I’m in the same quest at the moment. I’m thinking of going for the Scorpion. Did you try it?
