Stolen cat converter w/Cali emissions

**As a disclaimer, I will replace the cat converter**

Bad two weeks for the XJ. Had the stereo stolen two weeks ago, went out of town for the holiday and there was a hail storm when I was gone so my hood looks like a golf ball. Then I tried to start it up and it scared the $h!t out of me. Looked under and the cat had been sawed off.

Can I replace the cat section with some straight pipe I have until I can get it replaced? I have the California emissions package, so all the o2 sensors are before this third cat with the two precats attached to the exhaust manifold. I was just wondering if it will screw with anything if I drive it for a week or two like that until I get the $$ to fix it.

Shouldn't hurt anything.

Although, you'll throw a code, as the downstream O2 sensor is looking for catalyst action. Wait, that's probably gone, too. Don't forget that!

Vatozone sells a cherokee specific cat-delete pipe for under 20$. .

That would be great, as I cant get my scrap pipe to work. The little a-holes cut the cat off really close to the crossmember. If there is a specific pipe made for this I can take it off and keep it for the next time they steal the cat.

I searched autozone website and google and couldnt find it, do you happen to have a link?

I guess they do not have it anymore? At least not on their site. I know that its 2.5" pipe, If you still have the forward flange, you can pull it and weld the pipe to that and use a clamp for the rear.
performance-curve.com has a universal cat under50$.

Flange is gone. They cut it to where the manifold pipe is just starting to bend towards the engine. I wonder if one of those sealing clamps (not a C-clamp) you tighten with two bolts would work....

It should work alright.

Read.

You can get a high flow cat from many places for around $70. I use [email protected]. Using a piece of straight pipe in the mean time will be fine. Won't throw codes, won't hurt the engine.

Those have no downstream O2 sensor. The 3rd cat has no O2 sensors around it. All 4 O2 sensors are located immediately before and after the pre-cats.
