B58 PPF/OPF resonator delete

Does anyone know if removing the resonator from my exhaust pipe throws up a cell..?

I know that 1 of the resonators is the PPF so i want to remove the other one!

Thanks in advance..!

No, it will not. There are no checks or sensors for the resonator. The downpipe is a different story with the O2 sensors in the cat

No, I have both resonators removed. No issues.

But with having both resonators deleted you have removed the PPF filter right..?

I thought the pressure sensors would detect the removal!?

Not in my experience

I have had a couple of different setups ranging from
Dinan midpipe + stock muffler (+/-high flow cat) (+/-vibrant resonator)
MPPSK + Catless/Highflow cat

All of the above remove both resonators and the MPPSK+Catless/highflow cat is essentially straight piped when in sport with both actuators open. No other forum members have had an issue with removing both resonators. Just be wary of drone.

Yeah, but i guess you had no PPF Filter (european car)...
