Overbought! Shindaiwa 600 SX for 4 cords/yr

after the mod makes a lot of noise, you use it as well?

The restrictions is the deflector no need to drill the internals unless you like stupid loud saws. @Team FAST did flowbench testing and just opening the deflector is worth 50% flow improvement.

I should get rid of the deflector. Chainsaw is running great as is, but if this'll make it run better, I'm all in.

The deflector is a great place to start, but gutting the muffler takes it the next step, and I always wear hearing protection so a little extra noise is a non issue. Try running a ported 372, now that is loud!!

Yes yes it is. I just got done running mine and it is louder than my 590 was.

in the end what should you do?
only the deflector or gutting the muffler

after the full mod how many rpm you have set? 13000
