V8V How to Tell if Performance Pack Installed?

[RossL]

I'm currently considering a 2008 V8V and the dealer is telling me the car has the engine performance pack installed. The pack apparently brings the car to >420HP. Are there any telltale signs that it's installed? One thing that is different is the engine manifold is black instead of gray like pictured here:

I also read that the performance pack has a switchable exhaust bypass valve allowing it to always be open. Where is the switch?

The only performance pack I could find was from Prodrive that Aston pushed a few years ago. I'm going to look around but if anyone has experience or can help me with telltale signs I'd appreciate it.

TIA

Thanks a lot for all of the help. The links to AMOC didn't work but I was able to dig around a little bit there and it seems the performance pack is pretty good for the 4.3.

Best octane I get in the US is 97 and from what I read that seems fine. Thanks again everyone for the help, I can't wait to pick up my roadster today!

Thanks everyone for the tips. I'm now the proud owner of a V8V

Looks great
But some one put the steering wheel on the wrong side
BTW partially open the roof and have a look at the ends of the middle support bar. The covers comes off and rub through the roof, get it checked!

Can you provide any additional details regarding the rubbing? And yes the steering wheel is on the wrong side

Thanks a lot Mikey and congrats on your Vantage S. I test drove one a few months ago and it's quite nice!
