Just caught this and like what you did to it?
How do you rate those tow mirrors? Where did you get them from?
Was the K&N worth it to you? Have you considered cat back exhaust or tube?
The tow mirrors are excellent, last I checked there was only a single vendor (Trail Ridge).
K&N definitely gives it more growel under load and cleans up a bunch of the engine bay. I left the exhaust alone as I freeway tow a camper a bunch and like having my hearing . Even the intake can be a little annoying through the grades honestly.
