And if you believe that this will land any small-scale first-time offender with anything more than a misdemeanor conviction, (WORST-CASE scenario), you are exponentially dumber than you're trying to make yourself sound.

With members like you, it's no wonder that people talk bad about this site. I bet I'd have to go back pretty far, (if it's EVER happened), to find a time that you've actually HELPED someone here. In fact, the last post I saw of yours was followed by someone making a similar observation. :nonono:
 
you're an idiot. Why dont you quit whining about your software piracy thread being locked. I didnt say that any piracy would result 100% in a felony conviction, I said that it is a felony and explained the law to you.

Not my fault people like you get butthurt when I tell them they are wrong. Remember you were the one coming to this thread trying to say it was a felony to modify a catalytic converter.

By the way, since you are on the subject, can you tell me what you have added to this thread or a way you have helped a member by spreading your temper tantrum to this thread? Trying to insult me isn't going to make your point any more valid or any more true.

BTW, why dont you check with the RIAA for instance about the kinda stuff that happens to small-scale first-time offenders. I bet you that it wouldnt be to hard to dig up to many federal cases against small scale first time offenders whether it is software, music, movie, or any other kind of piracy. Theft is theft. Dont try to justify it by saying they will be lenient if you only do it a little bit or if it is the first time you get caught.

Everyone quit hijacking the thread and take your unrelated discussion to pm's!
If you have a problem with how the site is run, do not clutter up threads with your rants. Take your issue to an admin.

Consider this a warning.

I came to this thread and answered a question from the OP, (specifically, I adressed how his exhaust would sound after the modification). I then warned of certain topic discussion, which, in the context of the thread, DOES involve driving a vehicle with a modified emissions system, on a public road, which, as you yourself stated, is in fact, illegal.

I'd have to say anyone who could actually read would be able to see that you and FIND were the instigators.

I was provoked and I retaliated. My deepest apologies.
 
seriously, stfu. I dont feel like playing with you anymore. I cant read? where do you get that from?

While we're on the topic of illegal activities, I wanted to warn everyone that just because THIS federal offense is open for discussion, do NOT assume that others are too. Also, whatever you do, do NOT mention the misdemeanor offense of beginner's computer hacking. THAT topic is strictly off limits.

The fact is that it is NOT a federal offense (felony) to drive with a modified or removed catalytic converter. It is a moving violation. You get a fine, not jail time.

It is also not technically illegal to drive a vehicle with a modified emission system, as long as the system performs as well as the system as required by state or local laws. Deleting your EGR for instance, while that is a modification to your emissions system, that is not illegal in most jurisdictions because NOX levels wont be changed to much by it, at least not to the point it will fail you. You can delete your precats, so long as your main cat is upgraded to a cat that will handle emissions better.

Yeah, keep insisting I am stupid. That will make you look good and keep people from noticing you have ABSOLUTELY no idea what you are talking about. You are dragging this thread down. Dont respond again, you will further confuse anyone who tries to read this. Besides, it is painfully obvious why you came to this thread in the first place, and you were painfully wrong.

Alright back on topic now: so gutting the main cat is butter huh, so just unscrew it or am i gonna have to cut the pipe to get it down?
To be able to gut it?
 
To gut the main cat, you would have to remove it, you can just unhook it from one side, and gut it from underneath the car. Just use a coat hanger or something to reach in and pull crap out. Better if you can take it all the way out from under the car, cause then you will be able to shake out anything that gets left behind. You may or may not be able to deal with the bolts without breaking them. You will need to replace the gasket between the flange. Gutting your main cat will make your car sound horrible IMO.

The precats are more of a restriction, but yes, the main cat is easier to do for obvious reasons. If you are unable to remove it to do the job, use a shop-vac to suck out as much of the leftover debris as possible.

Yeah, let's definitely get the facts straight. But first, stop with the name calling and provocation.
Not every federal offense is a felony. With the way you were talking down to me, I thought you already knew that. That's why I implied that you couldn't read - I said federal offense, not felony.

If it is not illegal, then why do emissions tests check for program reflashes and such?

The only thing I have insisted is that you stop talking sh*t and provoking me.

Mainly what they want to know is that you arent disabling CELs. Most reflashes are perfectly legal in states that test for that kind of thing. For instance, if you get a programmer for your diesel pickup, which is very common now days, many things will be changed that effect emissions (usually for the better I might add). I can't think of a single state off hand that will fine you or fail your emissions for using that aftermarket reflash.

This doesnt seem off topic here, but.... Emissions testing is not a federal thing. It is a state and local thing. This is why many states have no emissions testing. If you live in a state like south dakota for instance, the only way you would ever get in trouble with emissions is if you have a vehicle under 20 years old and you remove the catalytic converter. I can have my exhaust broken off at the manifold and the rest of the exhaust system just hanging there doing nothing, but as long as I dont remove it, it is legal. Aside from the inevitable noise violation.

Driving with gutted cats still illegal though, but here for instance, they never check for it.

And your qualifications are? I have to ask because no certified emissions person I've ever talked to, (including those I work with), has been able to tell me EXACTLY what the computer checks... especially at the end of the test.

Even if I stick and weld a pipe in there?

It is just in my opinion. Some people like the sound better. I think it gets raspy without the cat to mellow out the sound a bit. The restriction the cat adds really does seem to mellow the exhaust note, give it kinda a smoother sound.
 
High flow cats are dirty cheap, there's absolutely no reason to run without a cat. And if you're anywhere that requires a smog test(every 2 years here) to renew tags, you're only screwing yourself. Ever since I got my csvt I've been watching svt videos on youtube, and it's giving me the idea that many contour owners don't know what good exhaust sounds like. For example every modded exhaust on youtube(they all include removing or destroying the cats), sounds like a can of bees. Seriously worse than a civic with a 8" round ebay muffler.

I know the issue is what's been done to it, and not that it's a v6. I've driven a 3.1 chevy that sounded like a beastly V8. Even my old 2.8 Camaro sounded good.

Guys don't do this stuff, it's not worth it. The car ends up sounding horrible, it'll smell like fart(bad cats cause a sulfuric odour), you may not be able to get tags next year, and it's needless extra pollution.

come on now, they dont all sound horrible, although I agree there are a lot that do sound like shi-.

Well, I'm not adding much previously unspoken...but a hollowed cat (on the CSVT) does absolutely sound like total crap. After buying my CSVT, I assumed the absence of the resonator gave the whole cabin a irritating boomy sound. Adding a magnaflow back in the system toned it down, but it was later I realized my cat was gutted. I hate it and anyone wanting to try for themselves can have my hollow cat for free as soon as I can find the time to weld in a replacement.

As for the thru-pipe idea, I've never heard one...just figure it's not worth screwing with. I have heard from another CEGer that any of the non-catted performance y-pipes give a similar resonance as my gutted cat but haven't verified for myself.

See most people gut there cat and resonator. You can't do both...and expect it to sound good :nonono: IF you just gut your cat....your car will sound fine as long as you leave the resonator in place.:cool:

Also some states don't require emissions testing....and for polluting the air....we have pre-cats that do a great job!
 
Most states do not have sniffer tests that would be affected by gutted cats (you will usually fail these with true high flow cats too). Most just have the OBD hookup to check for readiness and CELs.
 
I can post up some videos for you guys tomm of my car with everything in place, without resonator and then a without resonator and a test pipe instead of a cat.

let me know what you want. Temps here will be around 50 so i you will hear rasp, Ill do a cold start and then drive around to show you
