hfc
 

Hey guys, so I decided to do some research on exhaust today...
Came across that hfc is illegal...
Now what I really want to know is, what happens if a cop pulls you over?

Like lets say the cop happened to be a 370z fanatic and knew everything about the mods that can be done. And points out that hfc was added. Is it just a simple fix it ticket or is it like severe ticket or wtf happens?! lol

Thanks guys =]

The worst thing that can happen is they confiscate your car.

You better use the forum search. This has been discussed.

I dont think the HFC looks much different then a normal CAT so I dont think there will be any problem. I would like a Cop or a judge prove that its a "high Flow" cat and not just a normal one. What is Illegal at least in the state of NY is removing a CAT that is I think less then 3 years old or has less the 50 or 60K in it. Something like that.

Or is damaged.

You live in a communist state, god knows what could happen, but the average cop is like anyone else. They don't want to do any more work than necessary, so shut your car off ASAP and he probably won't be crawling around on his belly on the side of the road looking for it. If he's that much of a Z nut, he probably won't write you a ticket anyway.

Unless you get the state trooper I did lol, he knew quite a bit about the Z and even said he owned a NISMO. Still didn't get me out of a ticket though. Iirc the federal law governs the emissions system and i think the fine can be up to 20kright. I would love to meet someone who has received a fine for putting in a hfc. I could see aa fix-it ticket, but I am willing to bet 99% of cops and emissions stations would see a cat and not say a word about it.

A lot of companies to cover their a$$ will put a statement like: "Not for public road use" or something like that.

You're right. The Northeast and CA are catalyst states for overt communist laws. An experiment to see how they can keep our whole country under communist rule. But don't get it twisted the South has a flipside social communism. We are screwed bruh. Screwed!
Dude get your high flow cats and buy an AR15 while you're at it! FTW.:driving::nutswinger:

Depending on what type of exhaust you run, the cop could give you a Ref ticket based on how loud your car would be but that is more common with cars running Test Pipes than anything else.

Really it depends on your area, some cities are more strict than others.

HFC is perfectly legal to have, I passed visual inspection in NY with HFCs on, they have cats... thats all that is required.

According to federal law though you aren't supposed to mess with the cats unless they get damaged or have been on the car for more than 80k miles.

Laws.
My job to break them.
Cops job to catch me.

Careful, the OP is in California and we have very strict laws on modifying smog related items.

As of 2008 all aftermarket Cats are illegal:

OP, I wouldn't worry about it since you don't have a few years until smog but really you run them at your own risk..

I kind of thought the same way after my post, I do know that CA is very strict with emissions. It's just so hard for me to understand how anyone would be able to tell that they are aftermarket cats, unless you know what OEM 370z cats visually look like, they are basically the same.

Yeah I agree visually it's very similar but noise-wise and emission test wise they would be able to tell.

Honestly though most people get popped for TP's not HFC's.

Most things to do with modifications on exhaust are illegal in California.

Everything is illegal :icon17:

Medicinal marijuana stuck inside a cat, producing a high flow ,would be considered legal though afaik.

if you have ADD, you can get a prescription for HFC's for your car

or PMDD, for your female readers

While I can't quote chapter and verse for you, I do know that California can be nasty about emissions issues if they choose to be. My feeling is that changes on street legal vehicles need to be carb approved or you are putting yourself at risk. So for the moment your bolt-ons are limited (about a 30-40 horsepower gain and more like a 100+ for the supercharger) to things like a Stillen G3 cold air intake, a cat back exhaust, an under drive pulley system and Stillen's recently approved supercharger system. Test pipes, high flow cats, headers (long tube for sure and probably short tube as well), and computer changes (as I understand them, some wiggle room may be present on this one) are all off limits. Having said that, if it looks stock it will probably get you through a roadside visual inspection if the car doesn't smoke or smell. Most shorty headers (maybe 7-10 horsepower) will "probably" go unnoticed as well but removing the cats is a huge red flag issue. The state has very strict rules about removing OEM cats so high flow cats are a no-no too. The one thing about HFC's is if they are actually delivering the required emissions (Note: HFC's are usually not CARB approved) performance they might go unnoticed (but not actually legal) and you might skate through. The thing about HFC's, test pipes, and long tube headers is they often (not always) cause computer and sometimes driveability (not to mention warranty) issues.

My advice is go simple (CARB approved CAI, pulleys and CBE) or go big (Stillen's CARB approved supercharger) but if you go another direction (and I'm NOT suggesting that you do, this is only a theoretical discussion) stealth is paramount or you could be screwed.

:iagree: this:icon18:

Just as long as you understand how the game is played.

If we elaborated on this topic further it would begin to break forum rules and possibly some laws in just the convo. :tiphat: but yeah. You shouldn't only know how to play the game. You must be a master of it.

Yes.

OP - I'll sell you my AZ tags once I leave the state. :tup: You'll be good through Nov 2012. AZ doesn't give a shit about their air quality. :shakes head:
