Have you heard of GMMG, if your in that price range allready, you should check it out, it sounds better than both to me.

Between Borla and Corsa, go with the Corsa. As mentioned above GMMG is great too.

www.ls1sounds.com

Go there and see which you like better.

Doesn't GMMG flow better too? Have you thought about maybe Magnaflow also?

Its all a matter of opinion. Your best bet is to find people with the diffrent exhausts, and listen to them, and ride/drive in them,and then make up your mind.

Personally, i don't care for Corsa. I dont care for the sound of it, seems to quite,and more rich guy sports car sound, where as i want a deep muscle sound

I've also seen issues of the insides of Corsa Mufflers messing up. Makes the car sound like it has an exhaust rattle, but i think somthing breaks inside the muffler(s). A guy with a 99 Z28 and Corsa has that problem. My dad's sounds the same way, and so does a local Z06.

Borla's are great, and i love the tips. To many people around here have them though. I have heard a few people complain that they get raspy, or crappy sounding if you have LT's and no cat with an open plate. Don't quote me on that, just what i've heard a few diffrent people mention on here.

I wanted somthing a little diffrent, so i opted for the GMMG exhaust, there is a Group Purchase going on right now, save 50 bucks for the standard tips, and 75 bucks saved when you choose the optional tips. Its still a lot to spend for an exhaust system (650/775 gp pricing),but if you really care about how your car sounds, it will be worth it.

And to whoever asked if the GMMG flows well, this is the exhaust that was used on the GMMG 427 ZL1

Someone welded up a cutout on a motor that made quite a bit of horsepower, and only saw "decimal dyno gains" so I'm assuming that its only a couple/few HP, so it flows excellently.

Sounds like GMMG is the better buy to me. Thanks for the info on the cutout and it's minimal gains too.
