I have recently bought a Janspeed exhaust system from the CAT back and am having it fitted by a local exhaust specialist, he has suggested that he will build me a CAT replacement pipe to fit as well meaning i can gain that few more horse power from taking it out of the equation.......the problem i have is that i would like to know if this will cause the engine any problems with tickover etc i know that the Lambda sensor is connected to the CAT but when the CAT is removed where will the sensor go???? and will it cause me makor grief? some people are saying no and some are worried it will ??
Pls help need it fitted soon!
