I'd say either run the exhaust all the way out like bluecajun said or put a bullet in series with the Aerochamber. That should take care of the drone. If you want to go with a different muffler though, I'd say Dynomax. I got true duals with Dynomax Superturbos and its got a nice deep rumble that's pretty quiet and has almost no drone. I also ran my exhaust at 45* angles behind the rear tires too so that helps as well.

 

[QUOTE] get rid of that dumb and run it all the way back with a tailpipe, like factory exit and you'll be fine...


Same advice here.

 

I decided on the 5x11x22 oval from Magnaflowwith 3" in/out and I couldn't be happier. After the Hooker, I actually had a Flowmaster 50 series SUV put in there because my exhaust shop (now ex-exhaust shop) said in wouldn't drone as bad if at all. It sounded nearly the same in the cab, while outside it sounded like it was blowing wind(read-like ****). I also felt a loss in my SOTP meter. I know, I know Flowmaster sucks but I tried anyway. The Magnaflow sound is much better in the cab even with it still dumped after the axle and sounds real nice outside. The difference in the SOTP is noticable on the + side. I definitely recommend this set-up if you don't like to hear your exhaust too much, especially in a crew cab.

 

Nice choice.
