F8 Finally!!!! Kline came out quietly with their F8 Exhaust

Mate its the same as the Pista. Its not going to be allowed as you are taking out your GPF's and the computers are not going to like that.

 

Looks interesting, do they have a solution for CEL like the Novitec Techtronic?

 

If your country requires the GPF, then stop reading this thread. You can’t even consider this option as you would be breaking the law of your country.

Here in the USA the GPF is not legally required by our nation. How will Ferrari North America view this? I hope that FNA will work with US owners, since I believe many will want to find a solution to restore the typical Ferrari exhaust music. Perhaps require the work to be done at dealership service centers, perhaps using a Ferrari co-branded exhaust. (I doubt the F8 exhaust is made by the factory anyway.)

As far as what I can tell by looking at the connections of the GPF to electronics, I believe there is a pressure differential sensor (to alert when the filter is clogged) and probably a temperature sensor as well to help monitor the elevated heat levels needed for the GPF cleaning cycles. (Raising exhaust temperatures, IMO, is not a great situation when Turbos are in close proximity.)

Reducing the temperature of the exhaust and back pressure, may or may not have an effect either as an improvement or as something which would require adjustments to other parameters. So others please chime-in.

 

Gpf or no, there’s little if any sound improvement for these 488 based cars. Look for v10 and 12’s.

 

The marketing manager at my dealership has told me they got FNA approval to install Novitec exhaust as long as the OEM cats stay in place, this was on one of the first F8 deliveries they had. When I wanted to move forward with Novitec, he told me FNA advised “standby for further testing”. Supposedly more info will be coming out this week after a nationwide FNA dealership meeting. I would also assume FNA will play ball with exhaust upgrades with this car as well, hopefully I get the green light this week.

 

Thanks for this meaningful update. I will make my interest known to my dealer as well. I believe in cats and don’t approve of having them deleted.

 

I’ll be ordering Novitec too, just waiting for FNA to approve it. However if they are still dragging their feet, I’m moving forward with it anyway.

 

The exhaust is exactly the same as the Pista unit. The difference will be what other items will be included in the sale to account for the removal of the GPF.

The sensors attached to the GPF cannot be left in limbo as the car most definitely will show error messages and probably go in limb mode.

If FNA approves such changes and something goes wrong do they still have the backing of Ferrari ?

 

When i say its the same as the Pista is that it doesnt take into consideration of whats different with the F8 that is the GPF. Its just rearranged set up. Image Unavailable, Please Login

If FNA approves the installation, my local dealer will do it and my warranty will stay intact. I’m assuming the GPF sensor tubes will be plugged to avoid debris from entering the tubes, the Techtronic plug in module will eliminate the codes from registering to the ECUs. Without the Techtronic plug in, you will get CEL codes but I’ve not heard that will also put the car in limp mode.

 

Ok thats great for you guys in America. We dont have that here as obviously lower volumes. Our dealers deal direct to Italy.

But with the sensors on the GPF they are tubes that go to electrical solenoids. Those solenoids are going to need an input.

What gets even more complicated is the whole process of the GPF with the way it works the regeneration cycle. I wonder if it the same as a DPF

The DPF collects these nasty particulates as we drive along, and periodically they are superheated and burnt off in what is known as a 'regeneration' cycle.

There are two DPF 'regeneration' cycles, passive and active.

In the case of the passive cycle the DPF warning light comes on signaling the driver that he/she needs to drive the vehicle at a speed nominated in the owner's manual or higher to generate the heat required to burn off the soot.

Hell if it is , i have no idea .

Whats interesting to note is that pinning the valves on a 488 GTB its effectively a straight pipe. With the Kline open valve and it still goes through a silencer.

I would have thought the best way to approach this is to have a replacement GPF with nothing in it basically a tube and what Porsche does and have a electrical circuit to take care of the readings from the tubes to the GPF.

I wonder as the F8 has the Pista engine. But what I'm referring to is they didn't / haven't tackled Correct. the GPF issue. Deleting it without and electronic component is mystifying.

 

Thats fine but just pointing out that it isnt like the valves pin them open ( and still not sure if someone has done that successfully without an error code coming up )

the function of the GPF is integrated with the ECU . Think of it like using a toilet , use it as many times as you wish but at some time you need to press the button to flush.

 

I doubt that also , but FYI the 3 Pistas that i saw non of them used the Kline value operation unit ????.

Maybe they do have the electronic component but not mentioned. But any interested party should send them an email and ask how they take care of that problem.

 

So regarding the pressure sensors, that’s a pretty easy issue. The pressure sensor is designed to compare the exhaust pressure pre and post GPF. When and not if the filter gets clogged there will be a pressure difference. If no filter exists then there should never be a difference and so no heat cleaning cycle would be triggered by the sensor. However the sensor need to report something. And of course the software may track driving data and trigger an automatic cleaning cycle which will look at temperature readings. But it would be easy to turn off the lines of software code for the auto heat cycles

 

As a custom job , i.e from an exhaust specialist , the way to deal with the GPF is a simple bypass.

This isnt something you can by of the shelf because no aftermarket supplier will do that.

Get rid of the silencer as anyone like me that pins their valves basically that's what you always have ( gives space to add bypass piping ) and bypass everything with same diameter pipe.

No CEL lights either for the Valve. The GPF will be there and still do their thing. The Ferrari mechanics will not pick up anything that has been changed.

One car that i build i dare say i fabricated over 30 brand new parts as there was nothing available.

If a pipe could be welded infront of the GPF even better as that part can be taken off the bypass welded on and refit.
