Gutting catalytic converters?

ahh yes yes there would be a temp sensor (to bring the exhaust overheating light on the dash im guessing) but isnt one of the key things to a cat the burner (heater element?)

Nope your probably thinking of the heater element in the oxygen sensor (lambda sensor). My 96 gtb only has one oxygen sensor and AFAIK the second oxygen sensor came in when cars fully switched to obd2 though in saying that not all cars have a second one to check if the cat is working properly

V7 have a o2 sensor past the cat and it's only there to check the efficiency of the cat

Removing it brings a code Altho can turn it off and it's gone

Does not affect performance at all

Maybe different for other models

Anyway if u decat v7 and keep sensor it does got bring any check engine lite or does not even report a fault in the diagnostics

Makes me wonder why the he'll they had it lol

Applies to jdm v7 and Nz new v7 as have tested on them 2'models only

My V7 hasn't thrown a CEL and it doesn't have a single cat in it...

Just a thought does your engine check light even work ;D

I suppose I could just disconnect the sensor on the second cat, and see if it throws a code from being too lean or under temp, but then I would need to reset the ECU to remove the check engine light.

Can you just disconnect the battery for a time, or do you have to go see the local subaru agent? I'm not a fan of Winger's subaru here in Hamilton!

Take battery out fir half hour and it should do an ecu reset

[Guest]

Its just a temp light, it has nothing to do with the ecu and you dont need to disconnect the battery. From memory they only light up when they go to ground so just leave it unpluged.
