Need way quieter exhaust now...

[Extended Power]

I built my exhaust using the Flow Master Delta 44’s in 3”.
The mufflers are under the box, not the cab.
I had the original Flow Master 40 Series in 2 1/2” before on the old engine, which had the mufflers under the cab, and out the sides, just in front of the back tires, and it was way quieter.
I thought the Delta 44’s were gonna be quieter, but aughhhhh...no.

I want quieter exhaust...I can add cutouts if needed.
The wife is not too keen on going for drives when it’s this loud.

Any recommendations?

PS: I used v-bands on the muffler inlets and outlets, so it should be easy peasy to change them out.
