I voted Corsa, I recently took a ride in an SS Silverado with Magnaflow. Although it sounded good, you could not hear yourself think cruising down the road. Way to much in cab sound at cruise.

Default Love My Corsa!

Straight through flow and nice in the cab.
I'm a hot rod of old. But now @ 51 years I like the quiet side of the leather interior while listening to XM radio. The hot rod part is my Radix and I feel the Corsa complements it nicely.
I looked at lots of cat backs and lost my shorts on a promised "Quietest Accessories Cat Back On The Market" from Gibson. The Corsa is the only one that pushes the in cab comfort, so I gambled and it paid off as far as I am concerned.
To each his own. I know lots of folks like to hear the results of their mods as they drive.

I'm looking for something with as little drone as possible because when I put the 4:10's in I will be spinning a little higher RPM at cruise speed. I don't feel like yelling over the exhaust drone to the person next to me. I like it to sound stock at idle as well (until the cam ). At WOT I don't care how loud it is.

I just got a Magnaflow 12249 and 12588 welded in series with each other. Quieter than stock, absolutely no resonance. Now I can hear all the little noises like wind and tires that I couldn't hear with the Flowmaster 70 Series installed (itself a very quiet muffler). About all I can hear now is the blower. Very nice, with the assurance that there is zero restriction on the exhaust now. Highly recommended.

Love that whine. You did not give us lots of time to hear it though. If you decide to do another. Start about 30 or so yards from the camera and let us hear it roar by in 1st then changing into second after it passes?

Mine has never had any drone in the cab with the corsa. Sounds almost as quiet as stock when cruising on the interstate. I hate drone in the cab. It sounds like . I know the corsa cost more but if you are looking for an enjoyable drive It gets my vote hands down! Mine didn't get loud until I installed the Headers and took off the cats. But you almost forget its there until you stand on the old loud peddle!
