Question Muffler/catalytic converter question on a 75 1.8 FI...

Hello Everyone,

I purchsed my 75 1.8 FI from California and it came with all the great Smog stuff. Since I live in BFE New Mexico where there are absolutely no regulations on smog (You should see the smoke coming from cars.. Well I think they are cars...) But... I have been thinking about getting a better heat exchanger muffler combination than the 1975.

My question is simple. There is a device coming out of the catalytic converter with a wire. That wire goes into the rear trunk and into a relay. That relay goes to the harness.

What the heck is this and can it be removed?

If I put in a 1973 Heat exchanger muffler combination it will not have this device or a catalytic converter. I am worried this will hurt my original 1.8 FI L-JET system or engine.

Thanks in advance,
Christopher A. Landt
