whats this wire on the standard downpipe.

[dohcturbo]

it leads up to a bunch of censors on the left.
dont remembering it on the type r.

can i cut it?

 

[kanye west]

Is it a lambda sensor :s

 

[dohcturbo]

there doesnt seem to be an oxygen censor either and the hole for it is wield up

 

[Turbo Tony]

i wouldn't cut it off just yet,

I have one on mine as well as the lamda,

Something to do with heat sensor or cat sensor, cant quite remember.

it's a cat temp sensor!!!. dont cut it off, it should connect to a connector in the engine bay, behind the air box and under a few sensors

 

[dohcturbo]

no cat in the new one so will i just disconnect it?

it connects to this plastic connector and disappears into a bundle of wires

 

[foresterdave]

leave it attached to exhaust-like above -follow it,it just clips out.disconnected mine last month when fitting de-cat downpipe.its on original + ready to swap back over for nct. i had no issues just plugged it out.
