Hello HT,

Long story short i have always been happy to delete rear 02 when using JDM 4-1 with the matching cat just by swapping to JDM P73..

My latest pick up is a 2001 and I would really like to keep the USDM ECU w/ chipped key but swap to the JDM 4-1 and the matching cat or any other option that will flow better and fit the JDM 2.5" flange.

Anyone have a magic solution for this one? Welded a bung on the JDM cat? 02 Sim?

Help? lol Did some searching but the nothing great came up.

 

Blox makes a $10 cel eliminator. O2 sensor plugs into it and it works like charm with a test pipe or high flow CAT

 

No sure how that helps me if there is no bung for the second 02 on the JDM car

After all these years I can't believe there isn't a plug for the electrical connector that does replaces the function of the sensor :s thx tho

 

Easy custom !

 

I just had a bung welded into place and that was about it.

 

Likely the solution I will go with... was just hoping there was a PnP solution by now lol

Just curious, did you bung the cat or the B pipe?

thx
