I was under the impression that new cars dont have to go through emissions until 7 years afterwards...at least in IL.

 

I didn't know the Evo was that old.

 

2007, comon......

 

having no cat is illegal so u have to have one if you want to be legal.
but your not going to be smog legal at all. Depends on what states require smog checks.

 

I just remembered when I was pulled over for my exhaust (no ticket, no warning), the policeman (in NoVA) told me: "technically, it's legal, since you have a cat (I have BR 3" Hi-Flow cat), but there are still noise considerations"*

*not a direct quote, but the basic idea!

 

I believe Il. is 4 years for the first emission the every 2 years thereafter.

 

Actually, a hi-flo cat has many purposes.

1) it doesn't emit that hydrocarbon smell that cops may notice
2) it quiets the exhuast note of the car a little bit
3) a 3" hi-flo is still MUCH less restrictive than the stocker, at 2.3-2.4 inches or so. . .
4) in states like Ca, where the fine for NOT having one is about 2 grand or so, its good to have one on visually, even if it isn't clean enough to pass emissions.


so, uh, its not quite like high performance drum brakes at all is it?

 

Emissions laws are state specific.

That being said, my Evo passed the Cali smog test with the GHL turbo back system installed....the GHL kit includes a high flow cat.

SC~

 

I have a place to go where they will test and pass modified cars... some will not.. best to keep your stock parts just in case. Though there are fines for driving with illegal mod.s, I have never talked to anyone who has been cited unless its something that was in plain view or otherwise obvious.

 

1) So, here in NJ, every car, motor, bus, any fossil-burning engine can be shut off, for a YEAR, and you know what will happen with pollution? Nothing, absolutely nothing. Know why? Because NJ is sandwiched between Philly and NY and even all the mid west’s industrial smoke blows over to our territory, NJ is powerless over its pollution.


But I should have stopped @ SO, because I really don’t care…

2) So, it’s a sports car, it is quite @ cruise, @ wot it is loud as hell, like any other serious sports car.

3) True, but still robs HP, like 15-20, not worth it IMHO
4) I don’t live in Cally, I am 3800 miles away…


Again even the highest of High flow cats are restrictions, that is what they do, the clog up the exhaust, high flow cat is damn near an oxymoron, or like High performance drum breaks.


Hey, look, I can roll my eyes too!!!

 

Wow... you live 1500 miles east of Miami in the middle of the Atlantic Ocean!

 

1st of all, I do not live in miami, went to school there, kinda why I use the U-MIAMI thingy.


2nd of all....

Get a map, and figure it out......

 

God, this isn't the first time we've disagreed on something, but you always insist on making yourself look worse than you need to. a bit sensitive are we? let me explain . . .


This is the WORSE logic i've heard in a while. Just because NJ would be a sh_thole anyways, even without its own pollution, if, hypothetically, you shut everything in jersey down, there would STILL be less pollution overall by definition.

Further, for those whose goal or intent is to lower emissions your logic makes absolutely no sense at all, b/c baby steps forward is still progress. Your logic would get everyone nowhere if one's justification for NOT reducing pollution is b/c it wouldn't make that much of a difference. That said, i could care less about the environment, but your logic was just so, uh, "disabled" for lack of a better word.



I don't know what it means to be "quite" at cruise, but im assuming you mean quiet. Anyhow, Youre, uh . . . missing the issue. We're talking about using a hi-flo cat. . . if you're trying to compare to other sports cars, the only way it would relate to what we're talking about here is if you are trying to analogize to other sports cars that also run cat-less. But that connection is never made. What are you trying to say? the M3 is a sports car, the Vette is a sports car, are they loud? sure. BUT THEY HAVE CATS.


It takes away about 10 hp, lets not be dramatic. Show me a dyno chart that says 15-20 hp.


Last i checked, it wasn't legal to run Catless ANYWHERE.






i made my point above, but ok...following your logic, and taking it to its full extent . . . ANYTHING that causes a restriction shouldn't be labelled as a "performance item"?

Well sh_t, you better be running a straight pipe then, b/c guess what smart guy, the muffler is a restriction too. And yet, we have "performance exhausts" that include mufflers. Anything that IMPROVES the PERFORMANCE deserves to be called a performance item, almost by definition. A hi-flo cat that flows more than a stock one INCREASES performance, so why shouldn't it be called a performance item?




you go ahead and do that

 

OH wow look @ this NOVEL you wrote, have to get ever point across or you E- Ego may be bruised, oh well lets see what you spent the last hour devoting to ME brought to this fine website.


This is Fact, can't argue it, sorry, try again and is well known in NJ. Pollution just rolls on in..

Who buys an Evo to LOWER emissions, sell your car and get a Honda or a Hybrid, keep trying...

Assuming you never heard a Ferrari or Lambo @ wot, very loud, pity. Many sport Bikes are quite Loud stock too, Harley?


Now were reaching, sorry, 15-20 is clogged up, especially up top, sorry But a different dyno on a different day and blah blah blah... .

Florida has NO EMISSIONS LAWS, none, and since there is no law to enforce it, well, you do the math.

The best exhaust for a turbo car is NO exhaust, you know this, you’re a smart guy who likes to argue on the Internet and Flex his E-Dick, come on man....As far as the muffler, Well Ii love that Fart Canon look with my 8" exhaust tip compliments my Neon and wiper nozzles.

Its not better, its "Less-Worse" Cats rob power, High flow or not. The name of the Game is to make as much power as you can, a CAT is an amazing restriction that can easily be removed, why replace? Its saves a $$$$$ and makes power, you like Hig flow cats, great wonderful,and it DOES quiet the exhaust down, but I would rather have more power. Different opinions, you know better to argue opinions, we may as well argue religion while we are at it.

Try not to get mad @ other peoples opinions and then posts novels to try to thwart their thoughts with E-Banter. But you gotta argue, its gona be your Job right???

 

Ok, got a map (from the Miami U Geography Dept.) and I've come to the conclusion that (despite the facts that you live in NJ and The Gators don't seem teach Geography) you live 300 miles south of Lima Peru, or in Papeete Tahiti, or in St. Johns, Antigua or somwhere 1000 miles north of Nova Scotia.

Anyway you look at it, you can probably use any pipe you want wherever you live, but we here in the USA generally must have a cat to pass emissions testing, and a Hi-Flow cat (which means RELATIVELY high flow) is our best option, if we want legal mixed with power.
