You never need to add more metal to a muffler. The stock mufflers are piles of crap IMO. All it takes is a little more fine tuning of the carb. The possibilities are endless on that muffler.
 
Here's one that Woodchucker owns.

Sweet!!! Fast SOB. :rock:

After I get done with the hickory I'll stick an 8x8 cant on the bench and see how it does. It's not getting a popup so I ain't expecting a speed demon.

So your saying I could cut a 2" hole in the muffler and it wouldn't be too big???
 
You can open up the whole of the depressed area and still be ok.

The stock deflector won't really make use of that much area even after opening it up as much as still looks good. I'll probably put another deflector on the recoil side. I like em to look good.

This is the deflector I added to my 026.
