Cat Delete

e92justin · 02-18-2011, 06:50 PM

I want to straight pipe my car. However i know you can only delete the secondary cats without having any issues. Any ideas on how to delete primary and secondary cats without having check engine light problems?

oxygen simulators will take car of the problem, but when It needs to be inspected, you will most likely need to find an inspection shop that will clear your car, since it will fail emissions tests

where can some O2 sensor simulators be bought at to fit a 3.0l BMW engine?

Well if you understand what cats do then you will once in a while have the smell of fuel in your cabin once you delete your primary cats, its not a big deal at all , just some people freak out over it thats all .. Ive ran many straight pipes lol so for me its not a biggie
