Feeling slightly naughty this afternoon, I am looking at exhausts for the 812GTS. On Fchat there are a few search results and Novitech appears to be quite popular. Does anyone here have any recommendations or experiences? Ideally it should be switchable but it's not the end of the world if not.

Usually I'm not that keen on obnoxiousness but I'm not doing long trips in this, and it may as well be as much fun as it can be if it's to be one of the last v12's.

You thought about leaving the exhaust and trying a Forza exhaust valve overide first?

It's both cheap, and entirely reversible so leaves the car stock, and you can decide how much noise you want!

Thanks Bertie. No, I hadn't considered that but I shall do. My son showed me a YouTube video of an 812 with a different exhaust and it sounded marvellous, so I thought let's do it.

Thank you for the link; whatever I end up doing I'll post an update here.

My GTS is coming in August and I’m intending to try one of these.

I looked briefly at Novitec for a replacement exhaust for my F8 but the cost is substantial and they need a gizmo plugged into the OBD port to stop it throwing errors. I can do without that hassle!

Was down at my local specialist the other day and they had a novitec fitted to a new GTS. sounded immense.

I put a sports exhaust on a TVR back in the day, drove out grinning ear to ear with the noise….

Drove back into the dealers to have it put back to standard 6 weeks later, fantastic for a half hour blast, became an embarrassing pain in the arse once you’d tried to live with it for a while.

Hence I’m not a fan of modifying exhausts any more.

Personal choice.

If you wish to independently control the valves, you'd be better off installing a Capristo controller rather than a Forza controller. That way, there's no risk of inadvertently leaving the valves permanently closed and damaging the engine.

As for exhaust manufacturers other than Novitec, take a look at Kline and Capristo.

The key benefits to the sound will come if you replace the stock cats with sports cats. The Ferrari manifolds and back boxes are already pretty efficient from a flow perspective so there is little to be gained by changing the back boxes and I'm not aware of anyone making replacement manifolds for the V12 engines. Ditto the use of an X-pipe. There's limited benefit in X-piping a V12 compared to a V8.

What’s the advantage of the Capristo controller over the Forza one?

As I already said,

"there's no risk of inadvertently leaving the valves permanently closed and damaging the engine."

The Forza one is automatic or always open I believe?

Also, how would them being closed damage the engine?

The Forza controller has 3 modes of operation - taken directly from the Forza website;

"Depending on application, the controller offers up to three modes of operation:

Normal Mode: The vehicle controls operation of the exhaust bypass valves. This is the stock mode.
Always Open Mode: Forces the valves to remain open at all times, overriding the vehicle's ECU.
Always Closed Mode: Forces the valves to remain closed at all times."

The Capristo only has 2 modes - Normal and always open.

It's the Forza's 'always closed' mode which is dangerous to engine health because it will create too much back pressure at higher rpm and result in lower power output, incomplete combustion and overheating.

Where is this info from?

I’m not convinced about how it might cause damage.

On the flip side, the Capristo unit in the pictures at least, has non automotive, unsealed connectors on the module meaning it has to be mounted carefully, plus it’s nearly twice the price.

Take your pick I guess.

Thank you. I made contact with Novitec and my estimate, without going through all the options, is around $30k for the switchable system including X-pipe, ECU non error making thingy, and remotes. They also appear to be happy working with my local dealership as well, which is a bonus.

I shall have a look into Kline and Capristo as well but Novitec seem to be keen and on the ball so it's positive so far.

I beg your pardon……it almost read like Thirty thousand dollars eek

Has the exchange rate changed, I've heard of £15k but not $30k

Well, when you say it like that...

But it's all relative, I mean Apple carplay cost $4k and I'm quite positive I'll get more use out of the exhaust. Not to mention the 'use once and forget about it' passenger display at $6k.

I think it’s more the fact that we’re used to Novitec exhaust systems costing around £10k, which is already considerably more than the Kline or Capristo alternatives. Given the strength of the US$, things from Germany ought to be cheaper rather than more expensive right now.

Perhaps the import costs have risen. Here's a snippet of the North America pricing list.

Ah, I see what's happened. You've shopped for the unnecessary parts and gone for the inconel versions which only confer bragging rights and little else.
You'll find that the Novi back boxes add very little to the sound compared to the stock Ferrari ones. Inconel does sound slightly different to stainless but you'd be hard pushed to spot the difference in isolation. The real magic in terms of being naughty with the sound from your GTS will come from changing the catalysts. I couldn't find a US price list but here's the Euro one;



The parts you'll need are;

Sports metal catalyst for cars with OPF €5,380
Bundled with Tectronic. €890
Switchtronic €580

Total €6,850 or, at current FX rates, $7,330

I've noticed that the Novitec USD/EUR exchange rate is 1.66 compared to the real life one of 1.07. On that basis, I'd expect €6,850 to come in at $11,500 which is much more in the realms of what other posters were expecting.

Whatever combo of Novitec this is would be my preference. Sounds absolutely mental!
