Muffler question

Recommended Posts

I'm the proud new papa of a 2000 DR-Z 400S and have discovered the previous owner had 'holesawed' the stock exhaust. WAY loud and probably no power gain. This may be sacrelige in this forum, but does anyone have any ideas about getting the exhaust note closer to stock with simple materials and hand tools?

Thanks,

Tony

Bear in mind that I have no idea what the inside of the muffler is supposed to look like! I removed the end cap and there is a tube of fine screen about an inch long that ends in a jagged cut. Looking down the muffler, there is a cannister of packing lining the edge. I can see all the way to the other end, unobstructed.

Sounds like you need a complete replacement muffler. But in the short term you can quiet it down some by bushing down the hole in the end cap to about 3/4 inch in diameter. Visit your local hardware store and you might find something to reduce the hole size in the tip. If you have a machine shop handy you can just make a reducing bushing and press it in.

Way loud is when you take the spark arrestor out of your RS-3 Full Yosh! :cry:
