F8 F8 Ryft exhaust cats overheating

Call Novitec since you have their part.

Good luck in the Ferrari dealership helping you with an aftermarket modification.

 

If it were me, based on prior experiences like this, put back to stock and recover as much of the original parts costs as possible.

 

I cannot say with certainty. Someone could answer that who resides in the USA but cat back means the removal of the GPF. Ferrari isnt going to like that.

 

In addition to being illegal for anything other than track use, the catback exhaust will give Ferrari ample legal footing upon which to deny any warranty claims.

 

This particular problem is certainly not covered by Ferrari warranty, as it's an aftermarket mod. No one knows for certain what the dealership position will be if:
a) you ask them to rectify this for you--my guess is they recommend taking back to stock and starting over and
b) in the future you make a warranty claim against an engine, exhaust or other issue that is believed to be the result of removing oem parts and replacing with mods and then purposely disabling the CEL/warning sytem--I think you lose here also.

 

This is why I'd never buy anything from Ryft.

 

So to be clear the GPF has been removed but the cat is the same? I had heard the GPF and cat were pretty much integrated into one piece as it is on the 812s.

I’m in the US and the dealers I’ve dealt with are very clear that Ferrari will not honor warranty on engine issues or check engine lights if an aftermarket exhaust is installed. I know about the magnuson thing etc but this is Ferrari’s position.

I would take everything back to stock.

removing the GPF is not legal under US law, notwithstanding the fact that GPF are not mandatory in the US until the 2025 model year

 

As others have suggested, the only sure way to give yourself the best position is to go back to stock setup. Even if you have the best dealer tech in the world who you always go to, it only takes one situation for them to go “well, hello there, this thing might not be our fault…”

Not Ferrari related, but back in my BMW days with the M4 I used to always play with various swaps. Everything came out when going to the dealer, every time except once. I had a situation where there was a recurring engine flutter, and the dealership had been having a hard time figuring out what was causing it. It would come and go, so even when they could see it they were having a tough time with diagnosis. One day I had the issue happen just around the corner from the dealer and “all” I had in terms of mod at that moment was an intake swap. I didn’t want to waste more time. It was brand reputable, nothing to do with what ended up being the actual issue. Surely they wouldn’t… they did. On that visit, they decided they could start charging me for all the labor they were having to put into the car and a bill of nearly 12k was presented after that visit (with still no fix, which ended up being a defective factory part elsewhere some months later). There were some words that weekend, it was annoying.

Anyway, moral is, it’s a pain going back and forth but that’s kinda the price we pay for tinkering with these beautiful machines. I would always go back to stock if going to dealer to get a problem solved. Anything more than an oil change or the like and I’m not risking the fight. Just one man’s experience and opinion though!

Stay away from ferrari dealer with that lot fitted,

 

Why don’t you get rid of the Ryff exhaust and just do a valveless Novitec muffler and put the OEM cats back on? It sounds incredible with just the Novitec exhaust. Once you’re past the warranty period then you can do the sport cats.

 

The OP’s exhaust is cat back.

This car is fitted with GPF. Clearly shows that there is an effect on the cats if they are removed. Adding an item to just get rid of the Cel does nothing to fix the problem , that is the cats.

Sure it can remove the Cel and stop it going to limp mode etc but it cant stop issues.

What are the chances Ferrari will entertain any claim that the over heated cats cause a major fire and no more F8 ? Zero IMO

 

So then how are dozens of people using the Novitec and other aftermarket exhaust systems without issue? I did a ton of research and the general consensus is that they’re error free.

 

Fitting the Novi catback removes GPF, you then get CEL. Either a remap is required, or the Novi OBD unit.

With the unit plugged in the exhaust is usually error free, but without it the car will have a permanent CEL.

This is the first gen which has this problem, 355-488 Pista could have catback with no lights - this all changed with the F8/SF90 gen of mid-V8s

 

Yes, correct. My reply wasn’t in reference to check engine lights it was in reference to overheating / high catalyst temp error messages. It’s really sad how muted and understated the F8 is with the gpf filters. It’s completely night and day with a new exhaust. I wish it came like this from the factory and especially consider US laws don’t require gpf filters yet.

 

Ahhhh! My bad, misunderstood you - apologies.

Yep, it's pretty drab as standard...but even that back box goes a long way to putting it right!
