Flowmaster 40 interior resonance and B-quiet

Where do your tailpipes exit, do you have an H or X in your pipes?

where are the mufflers located// if under the cab it might help moving further back under the bed

Thanks for the feedback. The pipes exit the rear under the bumper, H pipe and will be moving the mufflers from under the cab to under the bed, as they should have been located from the beginning. My dilemma is that while I am moving them, should I replace them with something with less resonance?

I have the same mufflers with a full 3 inch system on my 72 dodge challenger. The mufflers are just before the rear end and the pipes exit just below the rear valance. I have absolutely no resonance, with nothing more than factory carpet on the floor. I honestly think it's your current placement of the mufflers not the mufflers themselves. Just my 2 cents...

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

I actually did go to the flowmaster with another chamber (50?). The muffler is under the bed (hole thru the crossmember), tip dumps near axle under truck. I think it looks cleaner without seeing a tailpipe.

Do you think it would be quieter if tailpipe exited the side or rear of truck?
