Default Hey Lowcountry.......................

How did you resolve the CEL that happens with the test pipe installed on the 42draft designs DP. I talked to Evan at 42 and he told me about a guy who makes an adapter for the O2 sensor. Did you go this route or another? Thanks for any help.

Default Still got the CEL...

Waiting on Wayne to build me an angle block to trick the post cat o2 sensor. I've emailed him twice about it, but still no dice. Check the 42DD webpage for a link to Wayne's email addy.

Default You're going to love the DP.

Try buying an Audi Geniscan (less than 100 bucks) in the meantime. It will read codes and reset them for you. TTinCT also knows of some sparkplug related trick that can fool the post-cat o2 sensor as well to prevent CEL.

Default Some might call you too "Loud" after

depending on your cat back.
I'm 3" all the way with a small cheap resonator, probably a little too loud
