Seriously I struggle to believe the GT12 kit could sound much louder, and certainly struggle to see how it could be worth an additional £11,700 more.

Does it sound like this?

Turn it up.

I would honestly say its not far off! Bear in mind that I ran a de-fused V12V for 6 years, but nothing prepared me for the huge step up to the sound a de-fused V12VS with a cat-pass made! When I first opened it up to just 5000rpm, I said "OMG, WOW that sound is just mental!". Kermit is still new (now 200miles), so I'm going to give him a few more miles before hearing what max RPM sounds like, but it's going to be brutal I'm sure.

Is it 100% the same? - I don't honestly know as I'm inside the car and that is taken outside, but for sure its close - and for £800 vs £12,500 it's close enough for me to be 100% happy.

Hello Adam,

How noisy is the car with QS bypass pipes when at regular town speeds ?
Does the sport button still have the same effect of increasing the noise when switched on - and so is the car still ok ( more conspicuous ) for early morning start ups with sport deactivated ?

Also, what did your dealer say regarding warranty ?

Cheers

Northermedia has already covered the warranty aspects, so I've nothing to add to that.

In terms of sounds I have pulled fuse 15 out too - yes I know I am nuts! But I live in the city centre where ambulances race by every 15mins quite literally all hours of the day, so there really is no need for me to ever need a conspicuous exit. For sure the car was more muted with the fuse in before I pulled it out, but I didn't want to have to press the sport button every time as that changes the throttle mapping too, to the detremient IMHO, so I either had to install a bypass switch as Northermedia has done, or just pull the fuse. For me the fuse out, is fine - I'm happy to be anti-social. Lets face it nothing about Kermit is subtle, so making him sound the same was a no-brainer to me.

Besides I've pootled around for 9 months in a Porsche GT4 which, despite comments on the Porsche forum to the opposite, is one disappointingly quiet car, most especially when driving around town, so I needed a good healthy fix of AM V12 full-on madness again in my life!

That sounds like exactly what i am after.

Out of interest, who fitted your valve switch, and do you recall the cost ?

Info is much appreciated !

Buy from Clive - takes literally minutes to fit.

Hi Adam,

I assume you are referring to the secondary cats, yes?

Yes, just the secondary cats.

This is the Quicksilver part : http://www.quicksilverexhausts.com/Aston-Martin-V1... - there are similar parts for the DBS, but they DBS seems to have a separate part number, but both are £580+vat. You can look it up on their website easily enough.

Mine have already been done by BR.

I was just wondering if there was some extra noise I was missing out on.

Imagine how good it sounds without a roof

Indeed. Well I guess there is to some extent (unless of course BR have already done this too on your car), but don't forget that the V12VS has the sports rear silencer, as derived from the One-77, fitted as standard too so it already sounds more nuts than a std V12V or DBS, but then I'm sure the lack of a roof more than makes up for that!

I thought the sports rear silencer derived from the one-77 was on all V12V's? That's quoted on the spec sheet I fit with mine?

Nope, just V12VS not V12V. Thats not to say yours hasnt been upgraded by a previous owner though...

That's my understanding as well Adam. All I can say is there is little comparison between our two which has always led me to intend updating the noise on our V12VR if I ever get around to it. Not that urgent because they both make a great noise

Would seriously consider a cat by pass, but would worry about warranty on a new car

I agree with the result, but that is an extortionate amount of money for some steel tubing. There's no magic to it.

Any decent exhaust fabricator could make the exact same item for a lot less.

This thread details how this does NOT affect the warranty and how AM main dealers including "Works" will supply and fit these cat bypasses and give in writing that the warranty is unaffected.

I heard a rumour that Aston will be bringing out their own decat product range shortly. Will be interesting to see how pricing compares to that currently available from specialists but will doubtless not lead to any uncertainty regarding warranty issues.

I have asked to be advised when it is announced and they have pricing. Whilst I would love the performance pack the pricing really puts me off. If there had been a new diffuser with similar exhaust outlets to GT12 they may have been a different matter. A bit more noise is the biggest thing for me.

My Capristo thru pipes were about £400 from memory

Looks like you got a really good price as the RRP on their website is now EUR629, but I guess the pound was a lot stronger back then!

yep !!!

I've just looked and see what they call the muffler (the valved back box) is 4387 euros so that's basically 5,000 euros all in for the pair. At today's exchange rate, I guess that's equivalent to about £4,350 plus shipping. I paid £3,450 to a UK distributor, all -in, delivered directly to Stratstones who I then paid to fit everything

I have been quoted 17k for performance pack on new car !! Whilst would be cool, I seriously cannot see value in that. But as you say, would love the exhaust outlets similar to either GT8 or 12, just look so much more purposeful .

Would go decat, if going to sort exhaust sound as now it's confirmed won't affect warranty & at fraction of cost, seems the more realistic solution. Would like to hear a V12s decat first though.

"TITANIUM EXHAUST
The V12S Performance pack has an all new titanium exhaust system downstream of the manifolds. Incorporated within the system is a new design muffler developed using technology from the Aston Martin GT12, with improved gas flow which has been optimised to work in synergy with the new magnesium inlet manifolds to achieve maximum torque and power output improvements. Overall, the titanium exhaust system is almost 14 kg lighter than the standard steel V12 S system."

It seems it has a GT12 derived muffler but using the same exhaust tips.
I think I'll go for it when my car is due for its annual service in October. Along with the all-black instrument cluster from the GT8/GT12.

[CSK1]

I guess you could sell the old manifolds, exhaust and muffler to get some money back from the significant outlay for the Performance Pack?
