GMMG or Borla
id say gmmg, and i dont have even have mine yet, but from hearing them in person, i heard a stock manifolds with just gmmg, awesome, and i heard some lt's with cats and gmmg, even more amazing, so thats why i got mine, it really sounded good on any setup, even though i havent heard a ORY setup yet, but ive heard the catted setup sounds alot better with long tubes.

I'm very satisfied with my Borla. Closed on start up in the morning so I only wake half the neighborhood, and opened (with my MPP) once I hit the road. I've yet to hear a bad comment about the sound, matter of fact have been told by a few folks that they love to hear my car go down the strip......different, but a good sound. I've even passed the Johnny Law driveby and idle in traffic test with it opened....knock on wood...but of course it would have been a different story had I of had it at WOT and smokin' tires past them

Ive had both. The only reason GMMG is on my car now is because the previous owner installed it. I was very happy with my Borla on my 99. I think I may have actually liked the sound of the Borla better.

poorla ive heard gmmg on stock
and ive heard poorla on stock
and on a 427 ls? with a supercharger
and gmmg even sounds better than the 427
the 427 and borela is louder of course
but the TONE is with gmmg.
i can only imagine what that 427 would sound like with a chambered exhaust
