anyone know how?

I'm looking to gut my cats before Friday before I hit the track. Anyone know how? Thanks for the help.

Why not install new pipe in place of cats?



Oh, good chance a CE light will appear.

I imagine though, to answer your question, I'd use my carbide hole saw with the 12' extension.

Use a hammer and something like a long piece of rebar

hope you have the rear 02 sensors tuned off... just drop the exhaust and use an long screw driver... once you break a few chunks out it will come apart easier....

Did they go bad??

If they are still in working order, I wouldn't bother. I'd buy some used cats and gut those if you really want to. Then take your good ones and sell them,,,they have some value.
I tried this route hoping for some gain. Didn't do anything at all for my car,,,ET or MPH. I still have the gutted cats here in a box if you want to buy them and try for yourself.
All it creates is a really large area for exhaust gasses to get trapped and bounce around. I think it caused more turbulance than helping anything, or something obvious along those lines since my car ran the same.
