359 muffler continued

[Hornetboy]

Well, my replacement muffler has arrived and will replace the standard (non-cat) muffler that is on my 2006 359. It has a dandy side port in the new muffler. Would anyone like to hazard a guess what sort of performance difference it’ll make?

I heard these were more apt to set things on fire?

I sure hope not

I remember cutting a tree with a modded Stihl 460. The bark was smoking from enhanced muffler port. No spark screen.

Did it give you a definite performance jump?

It is not the performance gains that start fires- it is the lack of anything to capture any point of ignition.
Any "muffler" that is a box with no internals and no spark screening has the potential to start fires.

No doubt about that. I’m just aware that the 359’s are reputed to be very choked off and many say to muffler-mod them

 

[Bob Hedgecutter]

Yeah, the cat muffler saws are- but did they come to Aussie?
Most any saw can be "helped" with a bit of muffler modification- at the expense of higher exhaust noise levels, not just the 359.

Mine isn’t a cat muffler. I read here a while back that the quickest and easiest way to wake up a 359 was with a muffler mod, and that they are responsive to it.

 

[Bob Hedgecutter]

Yeah, the internet can be good like that.

 

[Hornetboy]

The reason I was given for the 359 being so responsive was that they are very choked off compared to the 357xp,

I believe there is no difference between the oem 357 and 359 muffler. So ur new aftermarket muffler should show the same results for both saws. If u don't have an Etech saw, I think you'll have a hard time noticing any perf. increase.
