SW installed, now DTC thrown

[MercThunder]

Hi guys, if this is a no-brainer, I apologize.

Installed my SW header-to tip system, and after a short drive, the engine light comes on. The DTC is a 0153 (O2 sensor slow to react). Is this something my tune will take care of? If so, I'll just wait until all the upcoming work is complete before talking to Marty.
Thanks.

The tune needs to be adjusted for the headers.

We generally do not recommend running the car with headers without the tune being adjusted.

Thanks Marty, I kind of figured as much. We'll be talking soon :)
