Did a few searches here and on the interweb, but really didn't turn up an answer I liked.

I tow an enclosed racecar trailer, and likely need an new exhaust soon on my '03 5.4 SuperCrew. Are there any aftermarket exhausts that are quiet and suitable for towing, or should I just get a aftermarket OEM replacement, or direct Ford replacement for my exhaust?

 

I run a Corsa with low drone, with a lil' bite when under load. True to what Corsa claims Love it!

 

magnflow is great as well, no drone inside at all.

 

I like Allied Resonators

 

Corsa for no drone, but they are on the pricey side. A 22" magnaflow exited in the stock location will suit you well.
