hello,

I recently bought a Brillelli 46gt from scott.

Now we've measured the decibels that engine engine makes, we measured 89 decibels at a distence of 7meter at half throtle on the outlet side, so you can imagine how many noise it makes at full throttle
The exhaust is just a simple can with a pipe, no chambers in it, nothing.
At our flying field the rule is to stay under the 80 decibels at a distence of 7meters at full throttle.

The main cause of the high noise levels is the exhaust I think.
So now I'm looking for a new exhaust for it and I'm wondering if you guys can give my some advice?

I allready looked at BMB and Krumscheid mufflers.
I also mailed Krumscheid, they recommend a muffler that go's up to 65cc, but they also have a 55cc version and i'm really wondering why they recommend the 65cc above the 55cc.

Does anybody have any experience with other exhausts on a brillelli 46gt then the stock?

kind regards remie

You might give Scott a call or email him. I thought he had a pitts muffler for the 46gt that might be a little more quiet.

I contacted Scott, he could make me a more silent pitts muffler, but that wouldn't be anough.

I'm going for a krumscheid muffler now, I allready ordered evverything.

still I would like to know what others are using.

kind regards remie
