I just swapped out sidepipes. somewhat unscientifically, i have the ipod app called SPL soundmeter. At highway speeds, my old pipes read 105 db when held inbetween the drivers head and the passengers. With the new ones, both kids said immediately, wow those are way quieter". imagine my surprise when we did the etst again and it read... 105. The noise is much lower in pitch though, so the perception of "noise" level is much less.
