You have to take out the catalytic converter inside the muffler. Take EVERYTHING out of the muffler and make it dual port, retune, then cut. For a lot better power delete gasket and open lowers, you’ll fall in love with the saw.
@@IndianaDoug yes but the the muffler on a bike goes behind the main exhaust, a chainsad doesn't have one, a 2 stroke needs ressistance to run good, so by giving it free outlet how does that improve it?
G'day Kev, that looked like a nice little Red Ironbark stick it would have made some fine 150x45 rails, you could split those blocks with an axe but judging by the way they cut it's tight 👍.

why take everything out of the muffler? a 2 stroke is supposed to have a lil ressistance
@@julianlaustsen1991get heat out faster. Less restriction, less heat, better flow, better performance.
@@IndianaDoug then why does dirtbikes have expansion chambers? if u free that up they run poor
@@julianlaustsen1991 expansion chambers are not mufflers, two completely different things.
