ok let me describe mine... i bought a 14mm sparkplug defouler from a autoparts store for $10, in the package there where two sections and two crush washers. bolth sections screw into one another... one screwes into the pipe where cat went and the other the o2 sensor screws into... bolth had 14mm threads on the outside and the indide. and bolth had a 3/8 hole where the head of the sparkplud should go... the o2 sensor threaded in so far that one needed to be drilled out... so i drilled ONE section to 1/2" and threaded the sensor into it. the sensor was now flush with the end. the other section was left undrilled. the section with the o2 was threaded into the section in the pipe... and tightened... they are bolth straight... and the wires are about 1/4 from the body...
and you??? please be as descriptive as i am... can you please post a picture... this is my 1 year anaversry with a defouler and i have not had one code yet... are you running a super charger or just catless exhaust??? some ppl with
