I must be getting old… Exhaust is too loud

[Derkperk]

Hey all. The drone from my MBRB 4” is killing me at highway speeds. The around town sound is the perfect 6.0 whistle and I don’t want to restrict it down too much. I’ve had the truck since new and the exhaust was installed shortly after. I’ve been looking into replacement mufflers and resonators. Anyone have success with knocking the drone out?

Here's the parts number to what I use.

AERO-4040XL

Thanks. Appears to have good reviews on XDP. Do you run this in conjunction with a muffler or as stand alone?

I currently run cat less and thinking to run the resonator in place of that.

Stand alone. There's no packing to go bad as well.

Right on. I figure that’s what happened to my MBRB muffler.

They do wear out. I've got a video of a 7.3 at 4k rpm with the above muffler. I'll see if I can find it.
