Hey guys,
is there a list of the decibal ratings for the slip ons that are available for the KLX on this site.
for example: Muzzy XX decibals, FMF xx dBs, HMF XX dbs...you get it.

I want to get rid of the stock exhaust can but need to stay around the 94db for the area that I ride.

All help is appreciated.
Cheers,
Rutrider

 

Well if you want to stay under 94 then the Muzzy is not for you. I don't know about the others but mine is loud. I do wish I could get it tested. They must make you run the bike up to a certain RPM and measure from a certain distance. Anyone know how they test these things? There was a free testing by the DNR a few weeks back, but I'm not driving 3 hours to have them say "you didn't pass and now you've been warned."

 

Staintunes full system is rated under 94 and for road use. My 2 Brothers hits 115db at full chat (confused its a MotoGP bike witha big bang lump,) it can be made quieter with various inserts, like I care though.

 

Test procedure:

Bring engine up to rpm that is one half of where peak horsepower is generated (about 3700 rpm for our bikes).

Sound level meter is held parallel to to ground at same height as end of muffler, 20" away from end of muffler, and at a 45 degree angle to the centerline of the bike.

There used to be a website that had many actual readings on variations of bikes and exhaust systems..........but I can't find it.

Here's the deal. I have a Dirt Rider mag from Dec 06 that has a pipe comparison. Just tried to find it on their site and didn't, but there is\are other tests of pipes there. Might be worth a look.

 

I'm with WestOz! Love my 2BR, bike runs best without the P4 insert which cuts 3-5 db out; ordered the P3 insert for when I run to the "city" as the "BIB" (Boys in Brown) like their tea money. Stock my KLX measured 94db at 5k; the 2BR is so much more manly. I need to measure it next time I'm home but it's gonna be up there.

 

What about the FMF powerbomb header with Q4 muffler?

 

I beleive my HMF is rated at 96db with the insert. Also I notice not increase in volume when I added the FMF PB header.

Note:
Whe your running the bike to mid RPM's in idle (no-load) your throttle is barley open when compared to a laoded engine. Meaning your moving less ar/fuel = less combustion pressure = less output................
Not trying to start exhaust output wars again but something to keep in mind.

First of what area do you ride? Do you have the legal figures? Its not what you hear, remember you are riding away from the noise. There are set figures for noise, espescially in the good old USA.(thank you litigation lawyers for clutch and kickstand switches). I know where you are coming from you dont want to annoy your friendly folks and the boys with ticket books and loaded and legal guns. Dont no what your DB limit is in your state but its a procedure that would cost multi-millions. If it offends you fix it !

 

As a side note my 2br0s lets the nosy neighbors no where I am and I have an alibi!
