CEL with Catless DP and JB4

Laserbeam...er · 02-14-2020, 02:06 PM

I feel like this has to have been covered somewhere but I have searched for about an hour and come up without a definitive answer. I have an F10 535i with JB4. Would like to run a catless downpipe, but need to know what will be required to prevent a CEL. Just a defouler? Or is there a way to make the JB4 handle that task? Thanks!

Works for me just with defouler post cat.
