I just installed my catless DP on my G80, with the IRL spacers, which did not work. Within 5 miles of driving my CEL came on. (these were 90 degree ones)
Went ahead and bought the recommended BDG ones (
http://www.bigdaddiesgarage.com/mini-cat-cel-fix.html) - this is the link I kept seeing, but hoping the 90 degree one wasnt the necessary one.
My CEL has still been on since it popped originally. I am about to install the BDG ones and hoping no washer issues with crushing the honeycomb.
May be a silly question, but asking since so many seem to disappear. Should I immediately clear the CEL when installed or should I wait to see if they disappear on their own?
