Anybody uses Borla catback.
I wonder what's the hp gain? I know Corsa cat back gains about 6hp and 7lb/ft. I checked borla's site they just say it's 43lbs lighter than the stock. So anybody has a dyno yet? I like borla cuz it looks good to me (4.5" tail pipe, correct me if I'm wrong). so plz anybody, I'm about to order one.
