2009 CTS-V stock exhaust vs. Corsa axleback exhaust
I strongly advise using earphones for this video for best audio output.
I compare the stock mufflers with the Corsa axleback Exhaust in my 2009 CTS-V (automatic) at
Revs at rest
Acceleration on the freeway
Ambient noise at freeway speed
The primary changes with the Corsa are loss of drone at low rpms, and
louder, deeper Exhaust tone at WOT.
