Renntech Dowpipes with 200 cell cats
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
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.
feel free to call us under 772.266.9023 or e-mail at mitchellf@renntechmercedes.com
We would be more than happy to clarify all your questions!
Thank you
Your RENNtech Team
