hi

i have a import my95 wrx sti type ra, i have bought a ninja fast flow sports cat to fit to it as old cat is knackered.i take it the hole at the top of new downpipe is for lambda sensor,but where is the sensor, my old cat only has a sensor which is smaller and at other side of exhaust.i think it is the exhaust temperature sensor if so do i need it as new downpipe does not have a hole for it.

any help would be great cheers

 

its a temp sensor mate the lamber sensor is in the headers.
when i put a down pipe on mine i welded the hole up and drilled a new hole and then welded the temp sensor in to it .
hope this helps .. chris.

 

cheers mate would it be better to move the lambda sensor to the exhaust and then block the hole up in the header and would car run ok without temperature probe thinking off just unplugging it as it looks like it would break taking it out



cheers
