i dont think the sideburners would be to loud as long as there not shortened. you could also find a db killer for another pipe possibly? just make sure its the same size (thinking its 2 1/2") most db killers ive seen can be had with a flange type mount which would work great with the sideburners due to the lip aorund the baffle (if you can call it that?).
