I bought the Corsa single out and love it! No drone once it hits 4th gear and no crackle/pop from a cold start.

Originally I was looking at a Corsa Cat-Back dual rear exit but they don't offer it anymore and never had it for my year of truck. I had to settle with a Borla, but it definitely wasn't a step down. I do like Corsa's tips more than Borlas though.

I was looking at the Borla as well, kinda liked the single out more since it seems to be less popular.
