i have just purchased a downpipe full de-cat ( no cat back )

but i want to know is that the downpipe arrived today but only has one O2 sensor this is position at the exhaust side.

should i have 2 holes for sensors, 1 at turbo end and 1 at other end

thanks in advance

 

I don't know whether this helps but, mine has a sensor in the centre de-cat only. There isn't one on the downpipe.

 

if yours is a bugeye wrx then thats ok for me bud. not too sure about were the sensors go but that helps me loads :-)

 

well got my de-cat fitted, took me blumming ages. yes the sensor is only in the centre section.


i just loved all the messing around with the heat shields.


well worth it. got a nice noise from the turbo now and its a lot better on the top end. still got the change the third cat yet and get a remap :-)

but im getting there slow
