Don't get me wrong. I don't even know if there's that much to gain out of that exhaust while still keeping the manifolds and cats'; I'm just saying

It's my understanding that exhaust is around 2.5", so maybe coming up to ZR1-sizes would yield better flow. I can't say I wouldn't want a 600 horse' Z28, though

I'm really only looking to get the car up to about 550-600 at the tires anyways, so it should be even easier to reach that goal, reliably, if GM can get the numbers that high
