I can tell ya that if you go with the 4040 where the cat was it will be loud! I did it and after pulling the horse trailer up in the hills a few times I relocated it to where the stock muff was. Its still fairly loud when you get on it but not near as bad of drone in the cab. If I read your post correct, I assume since you have the cat back duels you are going to replace the cat with the aero. If so I would go with the "xl" muffler. If you are going to put if aft of the cab just depends on how loud you like it. Just my 2 cents.

NO please don't go through that just for me, I appreciate the offer though ( hey I am sure many on here would like to hear that , even me too )
My truck the way it is now, when under load at about 1950 - 2100 or 2200 is when it rumbles the best ( loudest ) in the cab but still it does not bother us, we are not to concerned with the increase in rumble under load, just not sure which way would do the high EGT's the best to help keep them down.
IE: Leave on the MBRP muffler for the duals and replace the stock Cat with the 4040 or th 4040XL or ?

Ok
I send aeor an email and they got back to me right away with the info I was looking for.
Jordan stated that the 4040 looks more like a CAT but will be a lot louder, and that the 4040XL will quieter one.
Sounds like they will both be ok with my MBRP dual muffler, so I guess I have to make up my mind now, we realy don't mind the noise, or will we?, when we drive for anywhere between 6 and 12 hours staight while towing, hmmmmm
