My current stainless exhaust is very, very loud. Primarily for a planned trip to Germany (where they are very strict concerning bike noise), but for more than one reason, I’m looking for a more silent model. I would be very happy with your advice or tips for brands/types. I did search the threads but could not find a clear solution, or I missed it wink. My bike has a 600 Absaf engine, I did mount a cone type silencer last year for a week riding in Germany which was pretty silent. But not only did I lose a lot of power, the bike suffered from pinging when accelerating under load. I understand that a quiet silencer with no power loss and original looks is a fairytale and compromises are inevitable. Knowing that, I really hope that your combined thousands years of experience will provide a solution. All the best, and thanks in advance, Peter

I find the standard Goldie silencer to have a rather harsh sound which makes it sound even louder.
I had Armours build me a stainless silencer. Externally it is identical to the Goldie "twitter" silencer, the tapered section is empty and the parallel section has a perforated tube the same diameter as the tailpipe surrounded by stainless steel wadding.
It gives a nice deep sound and isn't excessively loud

Hi Andy, I’ve got exactly the same stainless Armours exhaust currently on my bike. I like the looks, the build quality and the sound, but it’s still too loud for Germany and probably for NL in the future too, with all the anti-noise actiongroups. A lot of great routes are already closed for motorcycles in the season, I’m afraid this is only going to be worse.
I’ve asked Armours to build me a more quiet version with more baffles. They do that, but understandably they don’t give guarantees about power loss and noise level. I hope to get hold of it soon and I’ll let you know the result. I also located a specialist in race exhausts over here in NL. I’ll contact him next week, maybe there’s a modern solution out there.

This silencer was built to my specification

Andy, I am impressed that you persuaded Armours to make one to your design. I have two of theirs hanging up in my garage, awaiting installation, if I ever get that far.

I don't like noisy bikes.

Hi,

I have both Eddie Dow silencer and standard silencers. There is certain difference between them. I´m using Eddie Dow, there is more power lower rews. I have tested those at brake benc. Eddie Dow is also louder.

I think at ABSAF they have more experience about different silencers.

Talked with Jan de Jong of Absaf today. He does not know a commercially available silencer that doesn’t limit the gas stream and has little exhaust noise. He emphasized that the gas stream of a big single is totally different from the far more steadier stream of a multicylinder. The only real solution is a large exhaust volume, but that does not do much good for the looks. And the placement on the frame requires a tapered model which limit the choice of silencer considerably. As a compromise he suggested to have a slip-on end muffler made. Also ugly but removable when the riding situation allows it. I’ll keep on searching…

Hi Peter,

Kees vd Starre in Loenen (Apeldoorn) does make custom exhausts, Kees does also know a lot about BSA Golstars (they build, tune, maintain the championship Gold Star from Jan Frank Bakker…well at least in the past)

Kees has his workshop next to StarTwin in Loenen…

He is not cheap, but the best though… he made several exhausts for me in the past…

Cheers
Harold

Hi Harold,

thanks for the tip, good to know a specialist in NL. I tried London Exhausts but was disappointed with the proposed solution, could have guessed that because they're more into BMW's. I've received a silencer that's specially made for me by Armours today. It's based on their standard model but Frank added baffles. I'll put it on my bike this weekend and post the results.

Cheers Peter

You could try Raysons Exhaust in Rochdale.

Thanks Bill, looked at their website, real specialists. Should be able to find the solution there.
Thanks, Peter
