Another inconsistency I found is with the NPP dual-mode exhaust option.

The GM Canada brochure shows the dual-mode exhaust as an available option only on the manual transmission SS models. I understand the dual-mode exhaust cannot be selected on the automatic transmission SS models because of the Active Fuel Management system.

According to the online ordering guide, however, the NPP exhaust is also available on the manual and automatic LT models, of which I was previously unaware.

So, effectively which of all these option specifications for the rear differential and dual-mode exhaust is correct? Are these differences only for Canadian orders, or are there errors in the GM Canada information? If anyone wishes to provide some much needed insight that would be great.

Thank you kindly.
