That's identical to my stock Beast muffler. Don't expect to gain a lot by swapping it for something else, because it flows pretty good as is. If you install a Mikuni 30mm carb (assuming you don't already have one), jet it properly and install a better air filter, you'll feel an improvement.

I've dissected two Beast mufflers so far, and they're an intelligent design. They're a bit restrictive, but not so much that you'll feel a dramatic improvement; just more sound.
