gutting cats

[Robinson2487]

Anyone ever done this? Any problems with sensors? If so,any ways to get around them. I think mine are going and for the price of the oem replacements i might as well find a new mark

I've heard of it being done before but you have to remember the driver side cat is attached to the exhaust manifolds so it's not easy to do.

I wouldn't gut them, They are there for a reason. Gutting them wont give you enough power to even tell. Gutting them will actually increase turbulance in the hollow chamber. Go have them tested for free at a muffler shop.

There are no practical gains, just look at the size of the pipe right after them. THey will however make the car sound more aggressive with them gutted. I just took mine out completely.

Well my car is 97. I'm not looking for any gains... for that matter i'm not really looking for anything really other than working cats. I just dont want to dish out all that money to replace them with oem cats. I know the driver side is attatched to the manifold but i dont mind the work if it will save me money and no other problems will arise from gutting them. Thats why I was curious what will happen if i do gut them.

Just currious, Why do you think they are clogged? Have you had them checked? What is the car doing exactly?

Why not put in a peice of tubing instead of gutting them? You could stand to lose power from gutting them because you would have a big hollow space that would slow you exauhst gases down. Slow moving exauhst gages means less power.
