Ditto on the droan/resenance inside the car. I put a Corsa in my Corvette and pland to do the same for my CTS-V. I know loads of Corvette folks that have installed both Borla and Corsas. Borla does have a meaner sound and better perhaps of you want the rumble but on long rides you've got the resanance from the inside to deal with. The Corsa with it's "PowerPulse" technology eliminates the "droan" from inside the car. Makes it more drivable. Personally, I would use Borla on a sunny weekend type toy and stick with Corsa for anything I drive daily or want to take long cruises in.
