Muffler & Resonator Install w/Empirical Results

[m-35tom]

good test, but i submit that the tried and true walker muffler has the same results and looks better.

Most of the noise is coming from the firewall, floorboard, and windshield. It needs a hood blanket, soundproofing sprayed on the underside, proper boots on the shifters & pedals, and Rhinolining or similar material inside the cab. Better sealing of the doors & windshield would also help.

If the above is ever done then I'll retake dB readings in the cab. My goal is to be able to drive it without ear muffs. Right now, I have not succeeded in that. 80 dB is my optimistic goal.

Yes it's ugly, but temporary.

ww that thing is huge, it makes your truck look small!!! I've got a dynomax muffler that fits behind the stock heat shield and while i don't have a db meter your qualitative results are exactly how i would describe it.
