I've seen this discussed on several other threads.

Just thought I'd post another 1st hand experience.

After installing the DP, and wiring in the diode, I'm glad to say I haven't seen a CEL in close to 600 miles.

I'm typing with crossed fingers.....and hopefully it will remain off, but i've got no CEL!!!!

I still haven't bothered to fix my CEL from the downpipe. I guess I'll cut off the extension and try the diode trick--my OBD2 inspection is next month, so hopefully it works for me.

Cut off the extension on the CP-E downpipe yesterday, and soldered in the diode today. No CEL or pending codes after about 35 miles! Before the diode install I always had a pending code by about 5 miles, and the light was on by 15 miles. Hopefully this fixes things for good...

Checked the IM monitors last night at about 55 miles since the diode install--the O2 sensors passed both the ECM self tests, so I should have no problems passing my OBD2 test next week. CPE should just use a reagular rear bung and include a diode with the DP.....
