The DA50/1060 RPM with 23-8 mejzlik is 6800.
The DA50/SL pitts RPM with 22-8 Mejzlik is 6700.
Just my observation, you mileage may vary.

The weight difference is very minimal and the silencing effect and smoothness of transition with the KS1060 pipe it outstanding. The 2 planes are not comparable, for an accurate evaluation both systems would need to be tried on the same plane under controlled conditions with the correct tools to measure performance.

I'd love to try a canister on the DA50 as well.
