Silencing a white bros mx4 exhaust?

[D3structive]

Does anyone know anything about this white bros mx4 exhaust? I would like to know if I can silence it a bit more. I plan on going to an atv park to ride but they have a db check and i'm sure it's too loud. Since they dont exist anymore I cant find info on it

You could just go out and buy a $5 exhaust plug and put it in when you go to the park for a cheap and effective solution.

Those are designed for when the motor is not running, to prevent water/debris from getting in the pipe. A motor won't run with the exhaust plugged.

Lol I must be going crazy I thought I saw someone riding with one of those. Don't mind me when I'm not sure I say some stupid things sometimes :P

Some companies make discs to go in the end to make the exhaust quieter. But with White Brothers being out of business, thats probably not an option.

You could contact this company and try to figure out if a DB Dawg would work for you.

Is the endcap removable?

No. It is essentially one big canister. The inlet side is what attaches to the canister itself.

you could make an insert that slides in and drill a hole in the bottom and run a bolt in it to hold it in

That's the thing I was talking about!!! Haha my bad!

Just repack it, you probably need a repack anyway. It will quiet things down a little and probably give a slight boost in power.

I was going to say the exact same thing as duneslider. Repacking makes it a little quieter and it should help some.

Even if you have to, you could always find a super cheap stock exhaust on here or ebay and get that to ride at that park.

I'll try and repack it first to see what happens. any suggestions on packings? I heard fmf packings are not too good. I will also be ordering one of those db dawgs internal silencers just to see. Im assuming I will have to put smaller jets in to compensate? I'm running 42/152 with the slip on and k&n with no lid

i had an mx4 on my 400ex. i loved that pipe:p

just repack it. you will be fine

Im positive if you found a alluminum or other metal cap to replace the cap that you have now, only with a smaller diameter hole or several smaller holes it will be alot quieter and easy to make.
