It gives CEL error codes.

Cats are monitored by the ECU, without them and one would expect a CEL...

Totally makes sense to me regarding this, but I mentioned this on JCR Instagram when they first came out with their Catless Headers and Jonny said it did not give a CEL.

Then an explanation from Jonny how a catless configuration works without causing a CEL would be helpful...

  1. What was done with the sensors previously monitoring the cats?
  2. Are they still connected?
  3. Were there any changes made to the ECU?

Thanks!

It looks like one of the ports may function as a O2 extender...look at the length.
I would also like to know how the EURO GPF monitors are deactivated or fool when you install GPF deletes.
BTW...You can code out the secondary O2 CEL via a ECU flash...but that's illegal and doubt tuners would want to do it.

Yes you're right not that far... it's just that when I go "south" it's usually with family and travelling in a boringvan! But I mght wake up at 2am and take a drive to Tunel! If I ever go I'll PM you maybe we can meet!

put a jcr exhaust in titanium on your minivan and you are good to go.

I’m sure they have an application for your minivan.

seriously, a tunnel run at 2 am ….it’s going to be close to empty.

with your OAP and your jcr rear section you might cause some structural damage to the tunel.

once you try it out you are going to be hooked…for sure.
