    First off, welcome to the mix.:)

    Have you tried searching youtube for any videos yet? Sometimes a guy will have the same saw as you, and have a nice walk through video of what's what, and what to cut/remove/rip out.

    If that's not the case, stuckinthemuck is right, someone will be along shortly to (most likely) walk you through it. I posted some pics of my muffler, and it wasn't long until someone showed me what to do.

    I had an 038 and believe they are very similar saws. The muffler mod I did was just to open up the baffle some more (unibit to add some holes) and I doubled the output exhuast size by adding some slanted fins (Dremel 3 or 4 slots and bend with needle nose pliers.). Be sure to pay attention where your new exhaust outlet will point.

    Take a look, with the 2 halves design it is easy enough to just take a peek. Post some pics and you will get some ideas.

    Yep I did a 028 super one time and that is exactly what I did. Saw definitely ran better.

    You can weld a new pipe or deflector on the outside as well as open up the current one

    Duane after you removed the cover did you cut the baffles out of the muffler?,not the outer cover but the one inside with all the holes

    Yes, and it works wonders for letting the saw breathe. (it is louder but I always wear PPE) You will need to give it more fuel through adjustment of the H screw, and it will really purr...

    muffler mod..JPG This is what I put on my 036. I think it would work on the 028 too. The deflector is a husky part that screws on vs. welded on. My 028 had gills in the area where the deflector was welded so it was sort of a salvage operation.
