Guess i'll keep an eye out for it. Mine has been notably louder than the old 36 since day one, but that's expected since it's a bigger power head. I'll buy a quieter muffler just as soon as that becomes a reality.

I've blown out two in a row. Finally welded my own outlets in it.

Is the 40 really a bigger powerhead? I thought it was just efi and better heads that made it 4hp higher.

Not a bigger block from what I understand.

And those stock exhaust are a good bit louder than the 35's & 37's.
