I think D&D's are pretty nice pipes, and are well made. They're on the louder end of the scale. You just have to keep the chrome midpipes, inlets and endcaps clean or they'll eventually start to rust.

Do the bafflectomy like nath said, in stages. That way you get the sound you want. I've done a few and eventually went as far as nath said, plus I bought a super long drill bit and drilled a bunch of holes into the next baffle in as well. If you want a noise level similar to an aftermarket set of pipes that'll do it. Like he said you should be wearing earplugs anyway-you won't fatigue as fast and you'll also save your hearing. They cancel all the wind noise out and you just get the lovely sound of the exhaust on a much lower volume. Only took me a ride or two to get used to wearing them.

One other point, be careful if you start beating on anything inside the pipe to get anything loose as you can dent the outer skin of the can if you're not careful.
