Have fitted a decat HKS exhaust, up pipe and down pipe to my 2001 wrx uk300.
Now when every so often my engine management light comes on and when i take it to be looked at they say that the 02 sensor can detect more exhaust gases so turns the light on.
The car has been remapped and limits are at the uppermost they can be, car seems to be running fine etc
Anyone else had this problem with exhaust and remap
Do you think my car is going to die?
