93 lc header or custom exhaust?

I ditched the PAIR system when I did the motor and relocated the 02 sensors to the 2 holes left in the exhaust manifold so I'll just block off the downstream ones.

Hi Dan,

Thanks again for your concrete reply. FYI, since in my country cats are not mandatory for vehicles 1997 and older I went ahead and eliminated mine a few omnths ago without problems, so that's one less worry. I was still planning to leave the holes for the o2 sensors, but only of there is any value in having them there to begin with. I am planning to blank out the air injection ports as well.

Once I have the work done I'll send photos so that you and the rest of the MUD community can see. Regards,

This is exactly the thread I was looking for sweet! One question Longuito, u said you got rid of your o2's without any affect. I was considering just cutting the cats off closer to the cats than the o2's so I could retain them just in case. then run a y pipe and aftermarket muffler do you think that would work as well or just eliminate the o2 bungs like you did?

Hi trail Hunter, thanks for your post. Once i get started with my project I'll post pics. My O2 sensors are still there although there is no longer any cat, just a glass pack type muffler.

The only reason i keep them is in case i ever want to get back to (sort of) stock. I'll keep you posted. Cheers,
