F430 Sports Cats

Interested in the answer to this also. I've been told Capristo sport cats and headers combo is a good one but want to keep options open to learn more.

 

From a personal experience, I have figured out that if you have aftermarket headers then any sport cat will trigger a CEL.
Tried 3 different makes and had the same result.
Even had a specific remap that brought a total of 540bhp but still a CEL.
So now i went back to stock cats and got rid of the CEL permanently.

Now, bare in mind that some tuners will deactivate the sensors in the cats that trigger the CEL, but those sensors are there for a reason and shouldn't be messed with.
Also Capristo do this little gadget that tricks the sensors to thinking that the CATS are stock, but then again, it eliminates the operation of these sensors and if you ever have faulty cats you will never know and might have catastrophic results to your engine.

Having said that, everyone can make their own decisions.

 

We use 200-cell HJS catalytic converter cores in our 430 sports cats. These cores are extremely high quality and easily the best manufactured cores on the market at this time. While these cores have an extremely high flow rate, they retain the capability of filtering emissions effectively for most applications. That being said, while the vast majority of our customers using our sport cats on their 430 do NOT have a CEL, it is possibility that a CEL could be triggered (but not probable). The reason a CEL is possible is because some cars are more sensitive to change then others.

If for some reason your car is throwing a CEL after you installed the sport cats, an ECU tune will be able to desensitize the rear o2 sensor - along with providing a substantial power gain!

 

Capristo simulator only tricks the ECU between preset values, once a value is exceeded due to an actual fault a CEL is triggered, they would not sell a product that would allow an owner to unknowingly drive a faulty car.
I run Capristo headers, sports cars and muffler and although I have a simulator I haven't needed to fit it as no CELS have been triggered. (16M)

 

Hi Akshon,

I would say sports cats account to roughly a 10bhp increase and roughly 15-20 ft.lb.
The sound is also much louder, which I admit, I did like.
OK, I didn't want to mention this, but since Joe chimed in, yes it was Fabspeed HJS that I used together with their headers.
Don't get me wrong here, I am not trying to put down Fabspeed or their products, but this is coming from an honest customer point of view:
The Fabspeed Headers were brilliant and they even went into trouble to help me create custom blankets for them.
The cats though, although they performed as I have described above, they triggered the CEL.
My point is that, when it comes to sell these cats, Fabspeed should be honest with the customers and mention that it could probably trigger a CEL, rather than misleading the client, thinking that he can get away with spacers or ecu retunes.

To be perfectly honest, once I complain to them, they have taken the cats back and gave me credit for other products which I appreciate and I praise them for it.

Ok, What I have learned from this and I would like to share it is:
The car's ECU wants to see a reading from the secondary cats between 450-650 milliamperes.
Anything above or below will trigger a ECU.
Unfortunately, no manufacturer will guarantee that no CEL will be triggered and that also includes Capristo.

I have also bought their simulator and what it does, is that it records the readings of the stock secondary cats that the car has and then once you change your cats, it basically sends those old readings back to the ECU so the ECU thinks that the stock cats are still on.
Now, since these readings are already prerecorded Russell, even if the cats go bad, the readings send to the ECU will be the same, so their effectiveness is disabled.
I am very glad that you managed to fit all three items with no CEL.
You must be one of the very few!

 

I just installed the Hyper-flow cats and no CEL.
Stock manifolds and Capristo muffler.

 

If a supplier/manufacturer could guarantee that there will be no CEL with their cats ( if when they are installed together with catless headers) , then I would buy them immediately.
If a CEL appears, then they should offer full money back guarantee, including installation costs.
Whoever can confidently guarantee this, they will sell lots of sports cats.

 

Capristo can if you fit their simulator!

 

Everyone wants sports (hi-Flow) cats which are not as restrictive coupled with a robust set of sport headers. But nobody wants CEL or most would like to avoid the hassle of having to use a simulator or do a tune or something to have to trick the ECU. Manufactures should step up and come up with an "ideal" solution for a lightweight, robust, more free flow and power producing solution.

 

+1000000
Couldn't have said it better!
No gimmicks, spacers, simulators, ecu sensor deactivation, that handicap the ecu's ability to dedect potential faults.
Just a decent set of cats!!!

I hope they are all listening!

 

Hmmmm! Me thinks there is a misunderstanding of why a CEL is triggered!

 

The car's ECU wants to see a reading from the secondary cats between 450-650 milliamperes.
Anything above or below will trigger a CEL

 

If anyone has a set that they want to sell please PM me.

 

Just fit Redback Mini Cats, this will prevent a cell

 

I have capristo cats on my otherwise stock 06 430 and I have no CEL lights.

the cats slightly changed the tone of the exhaust - will probably add a capristo exhaust soon

one slight negative from installing the cap cats is the backpressure popping and rumbling has subsided a bit
