1973 450wr Quiet Exhaust

[FirstEliminator]

Hey guys,

The 73 450wr I have is really loud. It is going to be street ridden and used at some events where they may impose a sound test. I was thinking about putting some type of later silencer on it. Something used/cheap from e-bay.
Or, one of the questions I was wondering is, do those more modern style expansion chambers with the silencer give the bike better power and make it more quiet? Like the one available through Vintage Husky. I see they have one for the 400, will this fit the 450?

thanks,
Mark

I'm not sure about the modern expansion chamber type from Vintage Husky but this one from Vintage Sport will work. Only thing is I don't think it has a spark arrestor.

A long time ago I remembered seeing a post about after market or performance exhausts. There was a manufacturor mentioned and I didn't save it to my favorites. Last night, I spent a while searching and finally found Circle F. They make a pipe with a silencer kit for the 450. They don't have a direct picture of it on their site. They do have a pic of a Husqvarna with their pipe. It is different than stock, but it doesn't quite look like what HuskyJunk or Vintage Husky has available. Is it known if Circle F makes those pipes for them?
The Circle F pipe seems to be pretty affordable. Anyone use the Circle F pipe? http://www.circlefexhaust.com/

Here are the pics from the Circle F website.

Here is what my 450 exhaust looks like:

Here is the 400 exhaust from VintageHusky:

Has anyone used an exhaust like this? Does it provide better power? Does the silencer quiet the exhaust note better than stock?

Thanks for the reply Crashaholic. That looks like a silencer that might be a good addition to a stock exhaust pipe.
