o yea. it is db. sorry fast reading. okay ill take a look at the silencer. i really want that exhaust but i dont want the loudness even though i like loud bikes. its just all the neighbor complaints i would probably get. ha. it seems like its worth the money and a great performance upgrade. cant wait to get one!
There are 2 ways to make the pipe a bit more quiet that I know work, 1 is to use header wrap, available in a parts store, this will get rid of the "ting ting" dirt bike sound, the other is to remove the stock silencer,(drill rivets out), and install a longer/different one, I think 2" auto muffler pipe, some steel wool, and a 1/2" inner pipe(possibly electrical conduit) for the internal passage, drilled with a bunch of holes, or use chicken wire etc... Just a suggestion.

ok. yea the sbp pipe does come with a silencer so i guess it would be okay. i also see people talking about "poo poo" pipes. is that a name for the stock pipe?
The poo poo pipe is an exhaust system in where the header pipe goes to the back of the bicycle and the muffler mounts by the rear wheel.

Hehhe, ya, that was my post, DB is decibels.
The Xchamber sounds different, but as mentioned the SBP comes with one and not louder than stock.
If you want quieter you can you can just hose clap a lawn mower muffler on the end of that.
(@ Nougat) i believe that under 125cc is legal and its also a pedal assist so im okay.
(@ KCvale) ok, if the silencer makes it quiet then thats good. i really want one so i guess ill have to start saving up! its a bit pricy but i know the results will be good!

If You are getting the chamber also get a better air-filter and a MM intake from Pirate Cycles...take the time to match up the intake and exhaust ports..you wont be disappointed.

Motornut, it is good you disregard the bad advise about not being concerned with annoying your neighbors. You need to make your bike a silent as you can and hide the gas tank too. Unless you have a plate on the bike- you are not legal here.
I bought a basket- case old moped with a registration and my bike is now a customized Puch.
Go to the NYDMV website and see the requirements for a moped. There is no inspection for the 2 slowest classes of moped. This is a big plus.
Required- headlight, tail light and stop light. No "off road only" tires.
I steel stamped the Puch name and numbers on a plate and welded / blended it to the steering head. I ride it bike speed with occasional bursts to 25.

ill be getting a race carb before i purchase this. and i ride down side roads and along the curbs al the time and no cops bother me. ive actually rode by a few and they just look at me and keep going! so far im okay.
I don't know NY law, but here in Phoenix 48cc @ 20mph it is just considered a bicycle.
No ANYTHING like a drivers license or tags required to own and ride it anywhere you want, even bike lanes.
The thing is, the cops actually prefer you ride 30 on a 40 MPH road just so you are less of hinderence to drivers.
As far as engine size goes, well, all my builds have one motor sticker that says 48cc ;-}
SickBikes is out of Xpipes right now, so that may slow down your plans.
But back to quieting the exhaust...
I can't recall what movie I was watching last night, but the guy used a silencer on his pistol.
Now a gun barrel silencer certainly has nothing inside it to hinder the bullet travel like mesh.
This might give you guys some ideas.
How to Make a Silencer
If I had the time, tools and material I'd play with the basics but have none of those at the moment, but it is an idea to toss around.
Baffle the sound by bouncing it around in a double cylinder to cancel itself out and dissipate it through more holes.
