You only have to cut before the screw and cut the plate of the collector and weld it so that it is not very long.

As you will see in this picture, the screw of the O2 sensor is on top of the A/C compressor. You will have to cover the header in thermotec in order to not affect the compressor with high temperature. You will also have to make the holes for the O2 sensor in the header. Also weld some nut to put the O2 sensor.

are those pics on a 1.6 lanos? so other than making the bolt holes line up the header will fit in to the lanos? i see that it is tight but im not sure of what you mean by cutting he flange cause its too long, where did you cut? im sorry if i sound ignorant but i want to make sure before i spend the money and i cant use it, thank you

That is el junito 1.6 lanos. What he mean is that you have to cot the final are, were the o2 sensor is. and make it shorter. So that can be conected to the exaust pipe.

The same here with the tiburon (tuscani) 2.0. In a t20sed engine (mine by the way)

I cancell the project bacause I cant find some one who cut and weld the header conector (the metal part from my oem exhaust manifold).
