I'm looking for something to run in line with my aero or a muffler to run on its own but still sound good. the single AERO is just a little to loud.
I also thin that when I ran dual AEROs I got better fuel mileage
I have seriously thought about a donaldson 51"

I don't want to pay a lot for this muffler

 

I used the 4" straight through diesel muffler from SummitRacing on the 96 I used to have, I really liked how it sounded and it didn't resonate bad. they're not expensive, either.

 

I'll check them out.

 

it's PN: sum-630100 and is listed as a 'ford superduty replacement muffler' for $49.95

 

Summit also has a muffler by Dynomax its called a bullet. You can get them 4" in and out for 37 bucks I think..

I guess the price went up a little since I bought mine for my Cuda..
