i agree with keith.... i have the original 40 series... i got two mufflers right beside my driveshaft underneath my bed....i have hardly any sound of the mufflers inside the cab when the windows are rolled up... roll the windows down and it sounds badass.....i think like keith said that its probably the placement of the mufflers.....i also think that if you dont like the sound of the 40 series you shouldnt of bought the 40 series you should of gotton the ones that arent as loud....thats just my opinion
