2015 C300 resonator delete causes hesitation 1st/2nd and 3rd

I did a double in-line resonator delete and it caused a hesitation between 1st/2nd... and 3rd if you stay on it that long (sport plus only). Took it back and had the first one put back on. Problem is still there and will have the second one installed shortly. Has anyone done this and had the same problem? BTW it sounds like a turd if RPM's are below 2k so maybe someone thinking of doing it will read this.

Old post, but any update anyone? I saw many youtube videos of (only) resonator delete but nobody said anything about what the op experienced..

Can't see how a resonator could cause an issue. Maybe taking out a cat a would cause issues with the O2 sensor.....but anything after the 2nd O2 sensor shouldn't be seen by the ECU.
Strange????
