Removing Cat

[dr.ian]

Well, today I took off the EPBV. I took the flap and mechanism off and put a bolt through the hole that was left when flap itself was taken out, so it finctions the same as a spacer. Well, I decided to gut the cats while I was there. That was easy, it only took about 5 minutes. When I was done, I blew it out real good, so no particles would get into the turbo. All is back in place, and runs fine. I blocked the EBPV line, and the Throttle jacking line. I do not notice any change in sound. It really made my porsches sound different when they were removed. I have not driven it enough to notice a power diference. Does anyone know, will the car run and idle fine with no cat? Wil the O2 sensor give faulty readings? If so, do I just remove it, or alter it in some way? Thanks!....the chip is next if I can decide which one.

You'll experience no problem without a convertor. However, it might have been much better for you to have just made another exhaust and kept the old one around for emissions etc. if you needed.

You will not damage your O2 sensor. Under no circumstances should you remove it, as the computer uses this output to set the air/fuel ratio as well as timing,ect. This is the most important sensor(along with the coolent sensor) in a computer controlled car.

Did you follow the proper procedure with the cat?
