Exhaust threads are becoming the new oil threads.

 

The unthinkable non-popular option: Stay stock.

Every single exhaust made is loud enough to piss off your neighbors. Including the Yoshi, WITH the noise tube insert in. If you have to drive through your neighborhood on your Z at 6am, do the right thing and don't be a dick.

 

I think from everything I've read here and watching YouTubes that 10 out of 10 all say there all obnoxiously loud no matter which one you buy.
Not sure if all of them have a slip in baffle available or not , so sounds like thats a must to you.
Check to see what 02 bung they have to match your current and future needs (fuel controller)

Only a couple of them actually add HP, so more homework there.
I Only recall seeing the Yosh' and the Brooks with actual Dyno' proof but I'm sure there are more

But even the obnoxiously loud exhausts can be fairly quiet if babied out of your neighborhood or past a cop by only using 1/8' minimum throttle ...

There is a free mod thats is “just right” but your stuck with that toaster oven hanging off the bottom of your bike :grin2:

 

loud pipes save lives

 

grow some balls and put a pipe on it

 

Thanks for the advice. I guess it’s go loud or go home. I’ll just have to keep the revs down in the morning.

 

Eh... I had a whole thing typed up, but I'll keep it brief.

Pro-Circuit T-6: Relatively quiet, probably doesn't flow well enough for tuning improvements.

Graves Carbon: Relatively quiet, does apparently flow well, top dollar.

Kaw'ee $0.10 MuffMod: Might be good enough. Might as well try it before you spend your money.

GLHF, ride safe!

 

M4 makes a nice exhaust with a few stages of mutes....and made in Texas.

 

Good call. Do you have first hand experience with M4's silencers? From the videos I've watched the M4 has one of the best sounds, but still too loud for me with no baffle.

 

Thanks for the info!

 

I have an m4 and the stage 1 silencer that came with it, and it is rather loud. I keep going back and forth about ordering the stage 2, which according to M4 tech will hamper performance somewhat. I do love the quality of both the exhaust and the sound it generates, just wish it was a tad bit quieter.

 

I have an m4 and the stage 1 silencer that came with it, and it is rather loud.

Thanks for the response! I didn't realize the M4 came with the stage 1 silencer... explains why I couldn't find them for sale!

I was really hoping the Helmholtz chamber magically made the M4 a reasonable volume without a ton of constriction. Still, it's a clever design and a handsome pipe.

 

I have the M4 exhaust on my mine and I love it! It has a nice deep tone... an aftermarket exhaust is a must have in NY so you can be heard lol. And if your worried about your neighbors you can just roll it out into the street and take off.

 

I have always ran it with a controller but I have heard from reputable individuals that if that is the only mod you have done the M4 will run fine without one. To see your greatest performance potential a map is required.

 

Thanks! That’s what I was hoping for! It’s easier than explaining to my wife why I’m spending $1000 on a $3000 bike. Now it’s a much more reasonable $400. 😀

 

Just installed an exhaust on my Z125....
Found it on eBay for $115 shipped.
Looks great and the sound is deep but not too loud or obnoxious..
I put a video sound clip on my Instagram page recently if you want
to hear/see the pipe.
The name of the exhaust was Motoo and the seller was out of L.A.
My Instagram name is a1scoot.

 

Has it affected your top speed at all?

 

Minimal gain but much more fun when you can hear the motor a bit....

 

Slightly old thread but I'm wondering how that Anodized exhaust kit has been doing. I have absolutely 0 intentions of spending hundreds of dollars on a pipe and muffler for this bike so was looking at this option.

 

Most popular exhaust on another forum, sound great and seem to be holding up well so far... but there still kinda new.

 

I ordered it, will be delivered Friday.

 

I'm curious if anyone has any experience with the location of where the exhaust leaves changing the sound for the rider. Currently I have done the Kaw'ee 10 cent muffler mod. With where I have drilled the hole the sound waves are leaving directly below my head on a 45* angle to the left. Looking at pictures of the Anodized exhaust mentioned above, the sound waves would be leaving behind me and going straight back. My thought is that the sound would be pushed more behind me and I would hear less noise while riding. Not sure about my line of thinking, but thought maybe someone has hands on experience to share, or a lot better understanding of the science or physics of how sound travels.

 

Well, you aren't traveling faster than the speed of sound... so the sound coming out of the exhaust travels in all directions. That's why you can hear a bike coming and going....

 

Sound isn't directional, it's compressions of air that travel in all directions. Solid objects like cars and buildings can create "shadows" which give the impression of a directional sound, but motorcycles are too small to do this effectively and the ears you are worried about are directly above your sound source. The side exhaust probably has the more direct path to your ears.

So yeah, basically what crakerjac said with the addendum of "Everyone who has heard both an aftermarket exhaust and the 10 cent mod says the real pipe is heaps louder."

 

Thanks for the answer. That makes sense about sound traveling in all directions and objects bouncing the sound back making it seem like it's directional even when it's not. I was thinking more like a person with a bull horn talking to a group. The person behind the bull horn isn't getting the same volume as the people even or in front of the bull horn.

 

Ando, thanks for the video makes a little more sense. I could put a bell shape tip on my current exhaust and make it louder, but moving the place the sound exits 1 foot backwards is not far enough to notice any noise reduction.

 

Measurable difference, sure, noticeable? Certainly not. Main advantages would be weight and street cred. Though, there are a couple quieter aftermarket exhausts that may be easier on the ears than your particular holey-muff.

I rode a bike with the pro-circuit exhaust and thought the noise level was totally reasonable sans-ear plugs and I don't ride my holey-muff without earplugs even for a few minutes.

My memory could be crap though. I would definitely try to find a local owner with the PC T-6 pipe before dropping $300 on it.

 

Im looking to get an exhaust not sure if i need a tuner though. At some point i will get one im just looking to get noticed in traffic so i dont get ran over. lol

 

Just get the cheap anodizing racing version on amazon. Have put 1000 miles on mine since I installed it a month and a half ago, no complaints. Never ran it with the baffle installed either.
