take it to a muffler shop lol...search button....its 50$ but pointless unless they are really clogged...better of deleting resonators or mufflers for louder sound if thats what you want. No HP gains from this..

South Carolina too. We don't have any state inspections. People drive around with the corners of their cars all smashed up and maybe one headlight working. No mufflers. Might as well not have any turn signals either since none of the people down here know how to use 'em. Cops only use any of it as a bs reason to pull you over. Hell, I got a warning for having bald tires, and I've never heard of that before. But back on topic, I didn't think you could remove/delete the cats. I went to a muffler shop that's recommended by everyone and they absolutely refuse to straight pipe my 400 cause they say it'll mess up the way it runs.

What about cutting your cats open and gutting them?
Will this throw a code?
My mechanic and I both think that my cats are slightly clogged.
I ran my car for a month with a cam sensor issue(i didnt know) and mechanics tell me that it could have melted my cats a bit.
Please I would like to hear more about cat delete or cat gutting-----pros and cons.
Thanks---mainly will it throw a code--I have a 93 sc4.
And you would think that by opening the cats right up and gutting them that this would help with the air flow if even just a little bit-----am I wrong to think that?

I've heard that it depends on which cat you cut. From what I've heard, you can cut one off and not throw any codes. If you mess with the others, it'll make the car run funny. I don't know if that's true or not though.
I have a cat cut off and it doesn't give any check engine lights. It does shoot out a little bit of blue smoke when I start it up sometimes. No problems other than that.

Bought obx headers + the mid pipe that replaces all the cats. Didn't feel any difference at all and I believe it was a waste of $. I might be selling it soon actually.
I felt MORE power gains with an intake/headers/exhaust on an integra than on the SC, and laughably ridiculous amounts when I put a downpipe on my MKIV.
with the SC or NA supra, it seems like a great big waste of time, money and effort. It dosn't even sound great.

I kind of figured the power gains would be minimal if any, I was mainly looking for a cheap way to test the clogged cat theory.
Is it just me or does this dohc v8 seem way underpowered considering the other rockers toyota was building at that time? You'd think it would make 300 hp very easily (oh right, turbos).
I definitely can't complain about how smooth it is and the exhaust note is nice.
