Renntech Dowpipes with 200 cell cats

Hi
Just wondering if anybody installed the Renntech dowpipes( with 200 cell cats ) without going for ECU upgrade.

I was told that the check engine light will come on if the ECU is not upgraded.

Will appreciate your input guys

I would call Renntech to confirm.

Alternatively, Rado catted downpipes will not trigger CEL as posted on their website but no personal experience to confirm. I'm running Rado catless and tuned.
