I was really pleased with the combination of Borla long-tube headers, 3" catbacks, and hi-flow cats. Based on comparisons with my buddy SoCal Rebell who has the Belanger headers, exhaust, and hi-flow cat setup, I would say the two are very similar in terms of loudness and sound quality. The Belanger may be just a few dB louder, but the both sound ultra-mean.
At WOT with the Borla setup, the car just howls, and you'd swear you're in a Formula 1 racecar or the like.
It sounds to me like you should stay away from the Corsas. Trust me, they will be too restrained for you. Unless you are majorly worried about interior noise or resonance, the Corsas are not for you.
