Re: mufflers

run a glass pack up stream of the muffler, no drone. I had a magnaflush on my 5 cyl colorado and it sounded like someone burping in a tile mens room and drove you crazy enough to commit mufflercide on the highway. I put on a center muffler from a dodge diesel on it and it sounded much better. on my 65 I have a calsonic center muffler from a 350z and a magnaflush, and it sounds terrible, so I bought a smithys glass pack to replace the magnajunk. thats the last one I ever buy, more for the foxbody mustang guys that way.

you need to break up that long wave, thats what makes the drone is the frequency created by the pipes diameter and length. twirl a length of hose around in the air and listen, it will hit a resonant frequency.
