A while back someone talked about changing out their muffler and it was really quiet. Does anyone remember that?...did a search but too much came up
We were anchored out this weekend and ran it a couple times and it is a bit noisy.... probably more so for the people around me.
So I was thinking it might be a good winter project
I believe it was me... I changed to a Centex muffler (double the size of original lift type). And at the same time I replaced both sides of the 2” exhaust hose and all new hose clamps. This reduced exterior sound level about 30% (per my dB meter). I believe I posted at some point the actual muffler and who I bought it from... It was only about $160.
