Are these issues I am having normal?

[SilverRain]

I have had my Z06 for several months now and have noticed a few issues that I wonder are normal or not. A dealership I went to dismissed all of them.
Any thoughts on these observations?

1. When turning right and slow the car is very clunky. Feels horrible.

2. Even in track exhaust mode, the noise dies down when I am in third gear between 1500 and 2000 rpm.

3. My satellite radio loses the signal often. About three times every 10 minutes of driving.

4. In track exhaust mode, no air passes through the two inside muffler exhaust tubes.

Does everyone else get the same thing?

1. Are you talking about the tire chatter when turning at sharp angles at slow speeds? If so yes this is normal.

2 This is also normal. I bought a Corsa Extrem axle back and X pipe to make her sound like she means it. You don't have to go that far ... you could do just the axle back in Sport or Extreme or just the X pipe, or even go with another aftermarket exhaust.

3. There are a couple of spots near me that I lose signal, but they are the same no matter what vehicle I'm in. So that may not be normal.

4. Normal. Which the stock exhaust, after a few starts the inside of the outer tips will be black and the two inner tips will be clean.

So for the most part you're normal.

That's great, thanks
