ive been wanting to delete my rear cats but after farther research i found no info on how to replace it the o2 sensor is "through" the cat. does anyone have a right up or insight on this? im a professional welder and very confident i can do it myself

 

most people just weld a nut on the pipe after the cat and screw the O2 sensor in or make a o2 sensor delete with the Gotts O2 mod.

hope it answers your question

 

pretty much. cut 2 size. put in nut...guessing in same place as old nut. and tada

 

^ The gotts mod is NOT a delete.

OP. You will need to weld in an o2 sensor bung to relocate the o2 sensor.

 

whats the gotts do then>?

 

Search and read people!

Long story short, it will not throw a code!
