Any thoughts which sounds better?
Rousch or Borla S

 

My opinion is the Roush sounds much better. Aggressive yet smooth, and clear. My personal favorite on the 5.0L. The Borla is better quality as far as surface, and a richer smoother tone.

I have Roush on my 2013 5.0L, love the sound, but my only complaint is the drone inside is quite heavy.

 

What sounds better to you may not sound better to others, you will have to search for sound clips and make your OWN decision.

 

I know it's a different motor but I replaced my old Flowmaster on my 05 5.4 with a Borla dual in / dual out and the overall sound is a nice rich tone but the drone at highway speed is terrible. I've had it just about a year now and ready to just cut it out and go back to something quiet.
