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
Idle
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.

Hi Bob, I gotta say that I'm still on the fence about upgrading my mufflers to Magnaflows, I just don't see a significant difference in sound when compared to stock, did you get a horse power increase and if so was it noticeable?

[neuronbob]

@auxil47 I didn't have a baseline dyne before the Corsas were installed. I got 471 whp on the dyno after install. The sound is NOTICEABLY different in the real world as the sound is deeper. Also, the stock exhaust has an awful drone at 1500 rpm; it is non-existent with the Corsas.

Your neighbors gonna love you - hooliganism. I hope you don't live next to some senior citizens; they be calling the cops on you for playing NASCAR in your driveway.

Hooliganism? LOL! I'm a little too old and my ears too sensitive for that, friend.

Actually, the exhaust is not THAT loud except from behind the car, I wouldn't tolerate it myself that way. The Corsa Sport Exhuast is MUCH louder.

Hi Bob update, today I ordered the Corsa axle back mufflers, I'm sure I'll like them as much as you do yours , later Bob.

Thanks Neuronbob, I will be looking out for more of your videos. Now I just have to decide whether to get the Magna Flows like I had on my SHO which I loved or try the Corsa or the Borla, money will be a major factor. Have a great holiday.

@944devster I drive an 09' V and I'm 6'5. I used to own an STS and this has more leg room for me. Just make sure you dont get a manual, then you might have some issues lol.
