Exhaust Centre Pipe

[yemgi]

On the IS200 exhaust, there is a lambda sensor on the centre pipe, after the main cat section.

I have just received my new catback system (designed for IS300), but there is no hole to put the sensor in Isn't the sensor at the same place on the IS300 or is it a mistake of the pipe maker ?

The dimensions and fixations are right but I have nowhere to put the lambda sensor. I think I must put it back on to have the car runing correctly

Yes the lambda should be fitted back on the same position, because the ECU reads data from "Before CAT" and "After CAT" to calculate correct values for A/F mixture.

Don't know about the IS300, try to get some info about the IS300 exhaust, but as far as I know the IS300 and IS200 exhaust pipes are similar, except the header of course.

Maybe it was a fault by the exhaust shop.

If you could do it by yourself.... drill a hole and fit the sensor.

Or cut out the little thing from the stock exhaust pipe and weld it into the new pipe.

Just a suggestion,

I'm going to drill a hole and weld the sensor.

I aswell thought the Altezza, IS300 and IS200 have the same catback exhaust, only the header /main cat sections are different.

the is200 has the sensor after the cat, the is300 doesnt.

i dont recomend welding the sensor in

get a new sensor lug to weld on the pipe, any exhaust manufacturer should be able to supply you one

Thanks for the info on the IS300 Mat, that's what I was looking for B)

Don't worry, I have an other sensor on order :) It is the sensor lug I will weld
