Laws regarding gutted cat and straight pipe

[elrojo63]

I've noticed most people have gutted or deleted the cat. How are you passing inspection? In in pa and the law is if it came with one it's got to be there. I've thought about just cutting our a section and putting it in each time it goes for inspection.


Also required by law is a muffler. What are you doing about running straight pipes? I don't want to get pulled over and the cop to write me a ticket for no muffler or cat with.

Thanks in advance for the info!

Cat delete you cant pass inspection as for as I know. I did cause I know the right people. As for not having a muffler, Ive heard that turbo charged vehicles dont have to have one cause the turbo acts as a muffler. Not for sure.

well im not positive about the law but im runnen straight pipe to a 7" stack and cops seem to love it around here in southern md. but from my understanding about the muffler is that because we have a turbo we dont need a muffler. thats why the dodge neon srt-4 didnt have mufflers. but i belive they do consider the turbo as a muffler. for the cat i belive i read some were the befor 1998 cats are not needed? once agine im not sure about this just my understanding on it

If you look in the Parts books ,the 97 for instance lists no converter on some models made that year and some did come with converters.I don't know what book the inspection people use but they should have that info. Mine came with a converter and my Brother -in-law's 97 F-350 came without.

gut the kitty and put it on if you're worried. ha. im in nazifornia and running straight pipe. they tend to go after the ricers and dumb street racing kids here more than anything.

here is mo you dont need either in a 7.3. no cat is needed on a truck 8k gvwr and higher. and the turbo is considered a muffler here, you are correct.

Thanks for the info! I'm gonna call shops and say I'm buying a truck out of mo and see if they'll pass it when I get here.

there was a thread a while back on this. iirc, the vin had to show no cat its in configuration. so be sure to check the vin first. its the vin doesnt show that they will make you put a kitty on. im not sure if all vin specified that or not, there seemed to be a gray area in thread. let us know what you find. worst case, maybe they wont notice a gutted cat!

words to live by, i love the org for that very reason. agreed, there is a MO section in the forums, we got 'Show Me Strokers' up and tried for a meet but it never came together. the section activity has died off. one thing is for sure there are TON of nice PSD's out here, id like to see more of these people on the org. i saw Alberta7.3's truck the other day. - not really but looked liek his and was clean as new!

Just bolt the CAT back in before having it inspected. Bring it home and re-delete it and bolt the test pipe back in.
