Morning all

Ive just fitted a decat downpipe to me 1995 wrx import
The problem is the lamba hole on the decat is bigger than the one on the std cat.
What to do what to do
Does anybody run without one?

 

do you have a lamba on the headers? when i changed my downpipe was told it was the 02 sensor, just unplugged it and reset ecu, never any problems

 

Your Lambda sensor is indeed in the headers... I think the sensor you are looking at was fitted towards the bottom of your origonal DP & if this is the case then it is a "cat on fire" sensor which is now not needed. You can quite happily just disconnect this sensor and throw it away.

The hole at the top of your new DP is there for later cars which has the lambda sensor there instead of in the headers... You can fit a short bolt/plug to blank this off.

 

Ah quality guys..thanks very much
Im now a happy bunny
