Listen, I have 2 resonators and a muffler and there is still some volume in the cab. Not horrible but tolerable. If you want it quiet a straight through muffler won't work as well as a baffled design. Gets you a 51" Donaldson diesel muffler. That works for the diesel guys.

I can build you a resonator to kill the drone. It also reduces the interior sound pressure quite a bit at all rpms.

How much you will charge me and how you will do that ?

Now i have a baffle style flo pro 30 inch resonator

And the flo pro muffler and it still some drone .
If i remove the muffler and put a 23 in flo pro
Fiberglass it will not cut the sound .

PM sent. You would need about 26" free length to install it.

Ill put $100 it won't make him happy. Sounds like he wants a silent catless 4" system. No such thing.
