Wish I could help ya but it’s hard to describe in the cab. The corsa video on YouTube is spot on if you ask me. I’ve had Borla before and I feel like the Borla was more noticeable in the cab, but not by much.
I debated for nearly three weeks on which system. Finally got annoyed with myself and took a chance on Corsa. Super glad I did. I honestly think you cant go wrong with either option.
