I have the Borla Stingers (single trumpet per side)on my 02 vert 6 speed & just love the sound. Under acceleration great throaty sound & while cruising very quiet. I have the Corsa, not sure which model , on my 91 ZR1 sound good under acceleration but annoying drone while cruising.
On my 01 C5 I have had both. The Stingers had to go because of the drone. I run the Corsa Indy with no drone and are very aggressive when your foot is in it and quiet when cruisin all the way up to 90 or so.
Got the corsa exhaust and my bud has the borla, both sound really nice but over all I would rock the corsa, Looks great, sounds better. Makes the Race car rev when you throw your foot into it, but also dont have to be afraid of waking the dead when cruising at night.
I have the Corsa Pace Car exhaust. Debated quite some time between the Borla Stinger or Corsa. But, the Borla was quite loud compared to the Corsa. I didnt want to draw any more unwanted attention while driving.
