Not sure if this is the right area in the forum. But....I just got Richies (RV6) J-pipe and the cat delete (test pipe) but I noticed that the o2 bung was not welded on the cat delete (test pipe)...Is there a o2 sensor on the OEM cat? and if so, does it matter WHERE on the cat delete (test pipe) I have the exhaust guy weld the o2 bung on??

 

Never mind...Just spoke to richie from RV6 Performance. There is no o2 sensor on the cat. only on the precats for thoughs of you who havent checked the stock for themselves. And the test pipe will not throw a CEL! (Non Cali)
