I don't know what one is faster but I do know for getting work done I prefer a saw with a broad power band. Less pulling a stalled out saw half way through the log equals less strain on my back. Nice work on those pipes. I'm looking forward to seeing them both cut.

Pipe 2!!! They are both BEAUTIFUL

Pipe no 1 would better with longer bar in big wood Pipe no 2 shorter bar medium logs would cut quicker. I maybe wrong don’t know The real Dyno test is out in the Timberyard. Good video 👍

Depends on the sawyer and how it's filed

I think I'd like to try them both in the wood and see, leaning towards the torque pipe as the 592 has rev limiter at 12k or so.. I'd love to get one for my 592, its being sent off to Joe to be ported, could send the pipe to him as well to be dyno tested on the saw was my thought.

Torque pipe with bigger drive sprocket

👍👍

Please put a 592 cylinder on that 585 and see if the carb will make it run better please!!!!!

Well this is for the 585xp what about the 592 autotune? What kinda numbers are you making from them? Would love to see a stock/piped dyno comparison on 592 (I know from dyno joe vids that they make about 8.6hp from the factory, at his elevation)

I wonder if these guys make a pipe for a 390xp?
