Have had two out of the three. GMMG sounds good, sounds like crap with no cats IMO. Did not care for the Corsa, for the $$$ there were quality issues. I like Borla sound, never owned one though.

All are good systems but very different. The GMMG is more old school/muscle car sounding. Corsa is more exotic/higher pitched sounding. Borla kind of falls in between. Of course, I have Corsa so am partial to it.

never got a chance to hear the gmmg, but i got a great deal on my borla used, Still getting used to it, at idle now that the tune is better with the cutout open it is pure ear sex. Cutout closed on the highway it is quiet. On the stock motor it was perfect. Little loud with the 402, but not bad.

I love my Corsa, I spent many hours comparing sounds vs GMMG and never regretted my decision. It is rediculously loud without cats, but that's what I wanted. The rasp can be annoying, but I added a bullet to the I-pipe and it helped. If I was to do it over, I'd use a spiral flow or maybe an XR-1 instead of the bullet. Sound clips of my car are on LS1sounds.
