    Never personally modded a 550 muffler. I’ve been told that many of the new husky mufflers are a Bear to modify.

    There’s a way to get flow and some quieting effect, but you will lose some performance. You’d have to add internal baffles to make the noise hit other areas and give it time to cancel itself out.

    If you can look through the inlet and see the outlet it’s generally not great. Part of why I dislike open front covers so much.

    No, those numbers you posted already. I was surprised to see 9° blowdown. The transfers damn near open with the exhaust.

    Hey Backtroller what’d you do with that muffler? I told you I’d get you a stock one for it, hate to see it just laying on a bench or something.

    550 and 562 are both like that. I've come up with I think 10° on both of them

    Yup, but the first few degrees is the strato dump, so I guess you could say it's a bit more..

    He is talking about connecting the strato ports and intake some/all the way.

    Getting fuel mix in the strato ports.

    It’s with the saw and from what I hear the new owner loves it. I have to say the Craftsmanship on it was top notch and it did help power

    About the only thing I can think to say about a modded muffler other than it does help gain power, is if the outlet is aimed away on the off hand side of the saw from the operator, he or she will not be affected near as much.

    Ok good to know, I’d gladly trade a stock one back for it if it wasn’t being used. These dam auto saws are loud though with the muffler opened up, ear piercing loud! I wouldn’t think to run them without hearing protection

    With the stratos having a separate throttle body on this saw, how do you go about getting fuel over from the carb/intake?
