Aero turbine or Donaldson
Wanting to change up the sound of my 07 5.9L. Seems that Aero Turbine (4040L) or Donaldson are good choices. Any reason for one over the other? Just looking for a "throaty" sound but not obnoxious. I still have the cat so I hope it can still sound decent.

Aero Turbine is pretty loud. I ended up welding a Nelson resonator upstream from my Areo Turbine. Now it has a good throaty sound but still too loud to let idle in the early mornings without pissing off the neighbors.

Running a 5050XL, can not comment on the Donaldson, never ran one, it does seem to be a popular choice though on this board. As for the Aero, I have no complaints, it does have a nice throaty sound, but is is also 5 inches in diameter...

I had an Aero 4040L, drone drove me nuts while towing. If you leave the cat in might be a different story. Changed the Aero out for a Donaldson 51", much happier.
