Lightest 426 exhaust?

Anyone had their aftermarket silencers on the scales? My stock U.S. silencer (without the headpipe) weighs 8lbs on the UPS scale.

I can't say anything about Yamaha silencers but I have a Biggun exhaust systems mounted on my KTM EXC 520. I have 2 different silencers. One is equipped with a quiet core and spark arrestor, the other has only the spark arrestor.

Stock silencer weighs 2750g compared to 1600 respectively 1740g.
