BMW or XJ?

[rydizzy]

a: the $800 per cat ticket isnt cheaper then 65 bux for a magnaflow high flow.
b: says who?
c: i've never had to service my cat
d: nope, its been proven time and time again that this motor needs the cat
e: matter of opinion, personally i dont want my xj sounding like a honda b16. i know you do tho.


now purplecherokee...go troll some other forum. i hear honda-tech is looking for new recruits.

High flow cats are illegal for street use..just so you know. The only thing legal is an OEM replacement. And I'm not sure where you found a magnaflow cat for $65. On the magnaflow website they are $250. They don't sound anything like a honda without the cat.

I know why cats are there and when I gutted mine I had no money at all for a replacement and everything was broken up inside blocking the exhaust flow. Thomas now has this jeep and that's why it doesn't have a cat. He didn't take it out.

Then what does the DOT approval mean?

 

[rydizzy]

It needs to be EPA approved to be legal. The only cats that are EPA approved are stock replacement..not high flow.

 

[tharlanjr]

Funny, it's actually a federal law therefore still illegal.

Really?
So you.. uh have a statute number on that one?

1990 Clean Air Act, Section 203(a) Prohibited Acts, 2(e): (3)(A) for any person to remove or render inoperative any
device or element of design installed on or in a motor vehicle
or motor vehicle engine in compliance with regulations under
this title prior to its sale and delivery to the ultimate purchaser,
or for any person knowingly to remove or render inoperative
any such device or element of design after such sale
and delivery to the ultimate purchaser; or

Not to fuel the fire, but how does this apply to him?

Unless he sells the vehicle he is allowed to do as he wish's, but if he chooses to sell it he needs to add the CAT back to it.

I am gonna have to add this to the FAIL list...

magnaflow cats are 50 state legal...fyi. so they are legal for street use.

also...check summit...theyre around 70 bux for the cat i am looking at. they aren't that expensive.

The magnaflow site says...MagnaFlow Direct-Fit Catalytic Converters by Car Sound are designed for easy bolt-on installation for the Professional Installer. Each is designed to exact the original equipment specifications.

Original equipment..not performance or high flow. [/FONT]

 

[besthaticouldo]

ah touche.

however im pretty sure they flow better then the 13 year old cat on my xj now.

If you cut a cat apart, heat the matrix and throw a combustible gas at the matrix it burns. I'm gonna type slow, Brad help me here, I'm not the brightest. When you start the retard o mobile (with a cat) The matrix heats up, once to operating temp the exhaust gasses pass through and the matrix "burns" the unburned "fuels", it helps turn the carbon monoxide to carbon dioxide and water. You can burn gas with a hot cat matrix and not use actual fire. So in short, the cat helps US as stewards of our resources to keep the exhaust we put out at a reasonable level. I've been a mechanic for about 21 years and have "heard" of a total of 2 cats going bad. I worked with a guy that cut his cat off a truck, and was stopped by an officer that actually looked under his truck and gave him a ticket. The disposal of the matrix and it's contents is another issue in itself. I'm by no means a "tree hugger" I just understand that I do not "own" the earth, so I will do all I can to protect it for those coming after me, while I try to enjoy my time here. Did that explain how it works? I liked the pics, you should have taken it from the side

"Magnaflow's engineers have developed a revolutionary new compact catalytic converter design for use in tight places, such as on street rods or for custom car applications. Magnaflow fabricates each converter body from a single CNC-formed and laser-welded tubular section, which is then spun into a 4'' round converter body shape. Each converter is literally manufactured around the ceramic catalyst, which is securely tucked inside, and necks down to thicker gauge material at the inlet/outlet for maximum durability. Converters contain the properly loaded ceramic catalyst for optimum CFM and are OBDII 49-state compliant for engines up to 5.2L of displacement."

My cat is the only one I have seen go bad and I've only heard of it one other time. When I took the cat out everything inside was broken and piled up blocking the exhaust passage.

I worked with a guy that cut his cat off a truck, and was stopped by an officer that actually looked under his truck and gave him a ticket.

I actually put the cat back in..just empty. If a police officer looked, they wouldn't know that it was empty.

Yeah..I'll bet they do.

It also applies after it's been purchased. IE, if you purchase it and render the cat inop, you're wrong. Or in this case the original seller (rydizzy apparently) was the wrong one. I don't care all that hugely, I just like to argue.

yeah, well no,
Based on that "act" its prohibited for anyone to remove it.
What I was looking for was the Actual Statute from the Public and private laws, US statutes at large, or even the United States Code.
You see an ACT of congress must be approved, then signed by the Pres, in 1990 that would have been GHW Bush. But then after it is signed it is then put into the United states code...
The office of printing is in there somewhere an archive dude I think...
but after all that its coded and put in the book which is law.
Said law has a statue number and section that would be exactly what is written above if Bush Sr didn't line item it out.

Which he didn't, but the actual law is very elusive and hard to find. Where as the act that congress presented is popular because it has everything that they wanted in it. I don't know if that means thats what they got.

Actually, modern catalytic converters first convert NO and NO2 (NOx, key components of Ozone formation) into N2 (Nitrogen Gas, harmless) and O2 (Oxygen Gas, we breath this). It then takes the O2 (Oxygen Gas) and reacts it with any CO (Carbon Monoxide, deadly to life at very low concentrations) in the exhaust into CO2 (Carbon Dioxide, potentially deadly at high enough concentration).

This all occurs through catalytic reactions that are initiated by platinum and other precious metals.

Chem lessen for the day!

Mine went bad the same way. You could feel the heat from it through the passenger seat bracket, the engine would overheat on steep grades, but it would still pass e-check in California.

I took it to an exhaust shop, sure enough, cat was bad. I was unemployed at the time. $165 for a new Magnaflow OE replacement cat.

If you can't afford to put a cat on your Jeep, you can't afford to go wheeling, you can't afford the lift kit, etc. Use a little common sense, stop being a selfish child, man up, and do the right thing.

Also, motion to change Purple's user title to IDIOT BOY

 

[tharlanjr]

Doesnt that mean after selling it, but before delivering to the "purchaser"

ie, if I sell you a jeep its yours, but I havent delivered it to you, I take the CAT off, then give it to you, I am in the wrong.

lol

Thats just how I read it...

It also applies after it's been purchased. IE, if you purchase it and render the cat inop, you're wrong. Or in this case the original seller (rydizzy apparently) was the wrong one. I don't care all that hugely, I just like to argue.

Well thats an idiotic statement in itself, just because you go offroading, doesnt mean that your jeep needs to have a cat or be smogged, if its an offroad only vehicle you dont need a cat.

How many crawlers, buggies, prerunners ect have cats on them?

how many hundreds of thousands of dollars get put into those vehicles and they dont put a cat on them, are they idiots and should they not off road?

Try using common sence yourself...

slow down when you read

for any person knowingly to remove or render inoperative
any such device or element of design after such sale

meaning after you purchase it you can't remove it, you can't tell your mechanic to remove it, your mechanic can't remove it without telling you, NOBODY CAN REMOVE THEIR FREAKING CAT. NOT NOW, NOT EVER.

Last time I checked, we're talking about a Jeep that is registered and daily driven.
