Maybe I just haven't heard good enough videos of CTS-Vs, but I
thought Z28 was louder; it was certainly popping a lot off the throttle.
Regardless, like Elie says below, I know V's exhaust is pretty quiet, much from what I've read in reviews and comparisons. That's why I'm thinking we're getting less restriction, louder, and free-er-flowing exhaust. I don't have any proof, but
do hope we get a better cat' design

I just can't imagine that the Z/28 would have the same exhaust setup as the SS. I'm sure it would be noticeably louder...

I know that if it is a dual-mode, and controllable much like the 'Vette versions, and is close to 3-inches, I'll be saving a little money on a CB or even a AB. It doesn't sound
great to me, but it's certainly better that stock, and if there's a power gain to be had, that will be my biggest motivator

I think I remember Pedders saying they helped with air flow, too, hence their shape; I don't recall for sure though
Regardless - I'm happy with most any way reasonable for GM to control the weight and minimize it
