Cat Bypass (CEL & Stebro question)


Just want to confirm something before going forward with a cat bypass install on a 2000 base.. I have the two sets of cats and was still a bit fuzzy on whether or not replacing only the second cats will trigger a CEL, and what do I do with the O2 sensors once installed.

Also, (dumb question) where do you actually buy Stebro pipes? Just looking to price them, but can't find a place to buy them online. Places to buy other brands?

Thanks guys.

I have a 2000 base too. Replacing the secondary cats with delete pipes will not cause any CEL situations. All four O2 sensors are installed immediately before and after the primary cats that are integrated in the exhaust manifolds. So unless you are replacing the primary cats/exhaust manifolds you will not have to deal with the O2 sensors.


Best of luck,
