Has anyone tried or heard a truck that has the stack mufflers on it? I am going to be putting stacks on my truck, 4" downpipe to 5" muffler then up to the y pipe and into 6" stacks. Im leaving my current MBRP muffler under the cab for this set up but have also seen mufflers that go inside the stacks themselves. are they worth it and do they work? Im also just thinking about putting dynamat in the cab as well

 

check youtube. Ive seen vids of grand rock putting in 6in stacks with mufflers.... sounded alright to me.
ok so i went looking for it.... doesnt seem to make much of a diff on the vid. Though im sure its because its a camera and is gonna be loud no matter what... someone has to have them around here.. maybe?!

 

Thanks man, yea i have seen the video, and it is hard to tell probably cause of the camera and also they are in a garage. I think ill just load the cab up with sound proofing and throw my muffler under the cab and see what happens.....

 

Its hard to tell the loudness in videos. Personally I don't mind the loudness too much in the cab. If your looking for quiteness though it probably wouldnt hurt to have the extra mufflers but to tell you the truth it didnt sound to me like they made too much of a difference in the video. Got a friend that sound proofed his cab when he got stacks and it worked wonders!

 

thanks man, i settled on installing the stacks and then i will sound proof my cab at a later date. I personally dont mind the noise but i will have a young child in the truck occasionally and i dont want it to be to loud for that reason.
