the q muffler will give you a lower db level than the stock pipe as this muffler is longer, designed to put out 93db. the expansion pipe wont change the sound much at all, you will need to re jet the carb after changing the expansion pipe and going with a longer muffler, but fmf is good as they provide you with re jet info

they sound fine and work well, although the FMF or KTM Hardparts (same thing) SX style pipe has a better low-end hit. One of the best sound deadening items for a two stroke bike is a carbon fiber pipe guard. You would be suprised athow much of the raspy sound it quiets down
