i have no resonator and i need to cut my cat, what should i do with exhaust?

[mfuller]

Okay....that went downhill in a hurry.
Rule of thumb - if you wouldn't say it to your grandmother, don't say it here. This is still a public forum.

Lol...u mad bro? I go take my break and ur still here havin a hissy fit. Ill make u a deal...u stay on subject for this thread(for your own good) and explain to me why an engine needs backpressure and I will post a bunch of pics of my car soon( i guess its a widespread problem with people falsly claiming to own grand am gts, because it is such an exclusive car...) if not i guess u will have to just look at the pic on my profile til i choose to make time and post some...of course, i will post in the correct area.
Now since we are in the tech section, lets get back on the subject of the thread... Now u where saying an internal combustion engine actually needs backpressure...please explain the dynamics and physics behind this principle you have discovered and stop this child like bickering.

You should shut your mouth before you put your foot in it... again. Removing the EGR is not illegal. Removing the cat is... unless it fails.... stupid. Catalytic convertors have a limited lifespan. Same as the rest of the exhaust. The exhaust has a 6 year warranty from the manufacturer for integrity and function of the cat. If it fails before that, GM has to replace it... regardless of the 3 year general warranty on the rest of the car. Try reading your warranty sometime. You'd know that. If it fails after 6 years, you are responsible for replacing it. You can change it out for any type of cat you want... as long as there is a catalytic convertor on the exhaust it is legal. Try doing some research next time before you open your big mouth.

And at least I give enough of a **** about my fellow citizens to make at least that much effort not to pollute the environment that we all live in. That their children and some day my children and grandchildren will inherit. You sound like a typical conservative republican though... only care about yourself and only about right now.


Who's the hypocrite?

This is the most action i've seen on here in ages

I'm in Texas and removing the cat, egr or disabling it will fail inspection. But all we have in my area is visual inspection. There is no emission testing or odb2 testing near me.

[locoman99]

But aaron loves the children and is a great democrat and american so when he hits the dyno again he will have a ceramic core cat and fully functional oem egr system.

But no prob...he gots all that knowledge you know...n he is just an all around good guy.

[locoman99]

Good night and good luck

Whatever. I've never read anything anywhere saying removing the EGR is illegal. Removing it was necessary for my setup with the supercharger, as was modifying the PCV system. Also the thing about the cat and obd1 is recent. That was not the case when I bought it 4 years ago. At least I kept the PCV system in place, since it's good for the car and there's no need to eliminate it. That's better than most people on here who decide they want to eliminate the PCV and put a valve cover breather on. That's far worse than taking the EGR out, since it directly sends unburned fuel and combustion contaminants into the atmosphere. The impact from removing the EGR is minimal since I still have a cat and most of it is burned in there. So at least I TRY and make a positive choice.... unlike you, who don't care about anyone but yourself. I also ride my bike to work most of the time, so I'm not even driving my car that much, or using as much gasoline, and I obsessively recycle. What have YOU done to minimize your impact on the environment lately?

I would try shutting your mouth. That would greatly reduce the amount of air born pollutants being emitted. Want to keep this up? I can do this all day.

[locoman99]

Here is your link to the law... Clean air act. Yep u gotta lose your blower because of the dems...irony huh? Egr cannot be tampered with or altered. You should do some research before you open your mouth. Read it and educate yourself. After you get off your soapbox about how legal and rightious you are you need to get to work figuring out how to make your car street legal again.

I was gonna have this custom exhaust shop mke it so you can adapt a staraight piep in place of the cat, so you can put it back on if you need. How do you get it to run normal w/o a cat?

Did you even read the posts?

[AaronGTR]

Yeah.... I like how just because I care about environmental issues, that automatically makes me a democrat too.... even though I've repeatedly said I'm not.


If anyone cares to have the information (accurate info that is), the important part of a catalytic convertor is the core with the matrix which has a special coating containing platinum. That is the "catalyst" that starts the chemical reaction to burn pollutants. It doesn't matter if I have a metal core or ceramic core. They both have the coating so they both work. The difference is, the smaller the core, and the larger the holes in the matrix, the less surface area the matrix has to work. Therefore it is less efficient and also takes longer to heat up so it takes longer for the cat to start working on a cold start.

THIS is the reason why the link I provided earlier in the thread had a cat with a 16" core instead of the smaller 12" core available. It would be less likely to set a check engine light because of the larger core. Anyway a factory cat is much more dense and contains much more platinum which is why they are worth more money at a recyclers compared to an aftermarket cat. But you can still do alright with an aftermarket cat if you get it properly sized and keep enough heat in the exhaust. That's another reason I recommend ceramic coating for people with headers, besides the performance and durability benefits.

As for me, I could certain switch to a more efficient cat if I wanted, and since I have an electric cutout I can use at the track, it wouldn't make much difference. Anyone else could do the same and get the best of both worlds. Since I already have a working cat though, and have spent a lot of money on my setup already, I'm not going to change my cat just to satisfy locodouche's vindictive nature. At least I have a cat, and I'm not going around telling people to take theirs off like an idiot.

Now that that's settled... I don't think this thread is going to accomplish anything more, so it's getting locked. Make sure to thank loco next time you talk to him.
