Just stuff it full of shop rags.

I'll measure mine when I get home from work today.

Stock muffler pipe is 1.75"OD then it steps up to 2" as it enters the funnel. Hope that helps

I paid a godawful amount of money for the PMB quiet tip and Silent Sport exhaust packing and bought a YZ/WR 426 exhaust can because it's a little bigger than a 400 exhaust. It's quieter than it was with the aftermarket exhaust with blown out packing that came with it, but it's still fairly loud. I think I may not have put in enough packing; I'll get some rivets and redo it this winter. But what I'd really like is a really quiet exhaust like some of those stock street legal bikes so I can be a little more stealthy. And not annoy people.

That does, thanks. I'll have to get out and measure mine to see if there is a way to jam one onto my bike.


Thanks,

I thought your bike was very reasonable with the exhaust.
I installed a PMB tip on my Berg just to have the USFS stamp on the exhaust, the PMB tip actually made my bike louder than stock.

The first quiet tip I bought didn't do much that I could tell. But the second one I bought worked much better. I probably lost a horsepower or two but it was much quieter.

I used a dBdawg (from http://www.dirtwerkz.com) and it didn't quiet my WR250F a whole lot but it didn't reduce power either. i was running a YZ exhaust in the WR. I thought it was a good cheap tradeoff to stuffing a bunch of shop rags into my muffler or some $$$ billet exhaust endcap.
