RE: piggie pipe - antifouler method
I just used the Vast CEL Eliminators. Worked great for me and took all of 5 minutes to put on.

I agree just weld them in. Anti-foulers are just sending the ECU a false reading. With false feedback the ECU won't know if it's rich or lean toadjust the Air/Fuel correctly in closed-loop. You'd probably get bad fuel mileage while cruising.

The secondary oxygen sensors have nothing to do with fuel metering. They only serve the purpose of comparing pre and post cat readings to make sure the catalytic convertors are doing there job. This is strictly an emissions device. Without them hooked up or fooled you will get codes and your car will not pass emissions testing, nothing further. Only your primary oxygen sensors modify your fuel trim.

I stand corrected. Anyone know whythey didn't just place them downstream of the main cat from the manufacturer rather than downstream of the pre-cat?

its strictly for emissions to make sure the precats are working...
Thanks again for the input -
I found a place to relocate them to after the main cats...
I agree - better to just get it done right the first time....
From what I hear the DPs are a PITA to remove so
might as well do it right while theyre out...
