Hello All! I've been researching all the threads on exhausts for the 812 but would like some clarification related to sport cats for the 812GTS and the Ferrari GPF system. I've seen certain manufacturers (i.e. Novitec) sell sport cats with and without OPF but have seen some folks claim you can use the non-OPF Novitec sport cats on the 812GTS. I assume that the GPF is somehow incorporated into Ferrari's cats? Are there any sport cat options that incorporate something similar or does that just conflict with a desire for more sound and better exhaust flow? Do they all end up throwing CELs? I have read and heard that it really is the cats that unleash the sound as opposed to the whole set up with x-pipes, back boxes, etc. Warranty issues aside (which are a real issue), what do people recommend in terms of set up and the GPF? Thanks.
Your GTS cats have the GPF filter with them. You'll not have GPF with aftermarket cats. You will need to tune the ECU for the free flowing cats and no GPF or the car will not run correctly, possibly limp mode.
This is correct, with exception of the Capristo 250 Cell cats. These have been verified to have enough catalyst density to operate fine without throwing an emissions code. Several people on this forum have these installed. The Capristo do delete the GPF as well, and have a port for the OEM GPF O2 sensor to attach.
That's not quite right. It's not the delete of GPF that causes issues, it's using a sport cat (or no cat) that causes emissions issues. All of the aftermarket sport cat options delete the integrated GPF that is part of the stock Cat/downpipe.
Just to confirm - do the Capristo 250 Cell cats delete the GPF but still have enough catalyst density to avoid throwing any codes (including GPF-related)? In other words, can they be installed without requiring tunes or OBD modules?
I think capristo has a gpf integrated 250 cell solution that has no CEL with a GTS. There is a member here who has had this setup for a year without any issues. That being said, capristo vs novitec has a pretty different tone. Novitec has that very high pitch sound that capristo does not have.
That's interesting. Their website has the usual CEL disclaimer on the 250 Cel product page. I'll shoot them an email to confirm. Regarding Novitec, it's worth clarifying if the Tectronic module disables the GPF regeneration cycle as well (or just simply clears the codes) and if the module leaves a trace.
