Yep - the V8VS has a different back box than the V8V.
The S also has a black cam cover. I never really investigated the internal differences when I upgraded to an S, but according to a 2011 Motortrend article...
> The Vantage S is powered by the same 4.7-liter Aston Martin V-8 used in the base car, but now it develops 430 hp at 7300 rpm, and 361 lb-ft at 5000 - increases of 10 hp and 15 lb-ft, respectively. The extra power and torque come courtesy of a new variable-length intake system, and more aggressive spark timing.
So, there you go
I’ll have to refer to the Gaydon Aston “bible” for any further info.
Seriously, though, the upgraded sound from the back end made it feel 2x faster. In reality, I don’t think anyone will notice.
Even the GT8 only made an extra 10bhp on top of the S spec, probably all down to the exhaust?

If you want an extra 10 bhp or so on a standard 4.7 just replace the secondary cats with straight through pipes...easiest and cheapest mod, £500 and an hours fitting.
If you want more than that you need to look at a full exhaust system and intake modifications, probably including a remap too.

Cool thanks! Im in California, not sure how much I can touch the cats here. If you want more than that you need to look at a full exhaust system and intake modifications, probably including a remap too.

Changing the air filter seems like a quick fix with small performance gain.
On a 4.7 there are 2 pairs of cats, the first pair have sensors, the second do not. Usually the second pair being removed goes un noticed....at least it does for our emissions regulations/yearly check. Maybe check with other CA owners and see how they get on....

My understanding was that this is the case on 2011+ models. Mine is a 2010Top of the page here http://www.velocityap.com/Aston-Martin-V8-Vantage-...
