Hey guys, so I just picked up a set of lightly used APR dp and I already have stg 1 EPL. I'll be doing the stg2 with EPL once I have the DPs installed, but I wanted to know what else I will need to install DPs and not get a check engine light with EPL since they do not turn off any O2 sensors? I did speak to Chris at EPL and he stated O2 spacers and I know I will need O2 extensions since I did not get that with used APR DPs kit. I would appreciate if anyone can provide me with pics or links of what they are using and where they got it from. Thank you in advance.

Maybe call USP Motorsports for O2 harness extensions, phone: 725-221-5280
This Audi harness says it does not fit the Audi S6/S7, but then says two are required for the 4.0T: (https://x-ph.com/usp-motorsports-secondary-oxygen-sensor-extension-harness/)
