Time to upgrade my exhaust and I'm planning to get the Corsa since I've heard some good reviews about it. Does anyone have real experience with the Corsa exhaust? It's much cheaper than the Borla, and I can't resist the good offer from this site- Truck Accessories, Ford, Chevy, Dodge, and more Aftermarket Truck Parts. Just curious here about the sound of the Corsa and if there's any horsepower improvement you got from using it. Any feedback/suggestion is much appreciated. Thanks.
