Emissions Question

Ticket-Me-Yellow · April 21st, 2008, 11:37 PM

Alright so im gettin a new exhaust and i was wanted to go with an H-pipe with super 40's. Would i be able to do an offroad h-pipe and still pass emissions? is there anyway to not have cats and still pass emissions

no, you need cats if you have emissions.

Ticket-Me-Yellow · April 22nd, 2008, 12:07 AM

theres no way i can like go through and eliminate the check engine light?

Dansby · April 22nd, 2008, 12:15 AM

It isnt the light that will get you. It is a machine that tests to see how much smog your car is emitting. Thats what the cats eliminate. Many refer to it as the "sniffer" haha. If you have to pass emissions, go with high flow cats.

like a thing that goes in your exhaust? cause here in illinois they inly plug into your on board computer

tsp_2177 · April 22nd, 2008, 12:52 AM

if they look under your car though like i would think they should, you wont pass

Ticket-Me-Yellow · April 22nd, 2008, 12:54 AM

idk cause when i went there all they did was plug in to my computer and that was it

tsp_2177 · April 22nd, 2008, 12:54 AM

have two mid pipes and just change them out when you have to get an emissions check?

Ticket-Me-Yellow · April 22nd, 2008, 12:59 AM

04DSGV6 · April 22nd, 2008, 01:00 AM

yeah in Illinois they do not look under your car, just plug and go

Ticket-Me-Yellow · April 22nd, 2008, 01:06 AM

I don't know im curious myself. It says on the air team website that all the computer does is check for emission related codes in the OBD. I would say try it, save the stocker and if you fail just put it back on for the tests, if you don't fail get rid of the stocker. BTW what part of IL you from?

Ticket-Me-Yellow · April 22nd, 2008, 01:24 AM

Lake County. But im really temped to. I have to pay off a few tickets first

04DSGV6 · April 22nd, 2008, 01:29 AM

Heres a good read. Illinois emissions test - Page 3 - Corvette Forum Looks like with a tune you should be okay. I'm from cook county myself and I want to find a way around this eventually myself. Lemme know what you decide to do.

I dont have cats on my car, and all they do in NC is plug into the OBD2 if you dont have a CEL you will pass

98stangv6 · April 22nd, 2008, 10:24 AM

emissions testing is part of your inspection where they test the emissions coming from your exhaust

Dansby · April 22nd, 2008, 11:28 AM

Dude, in all honesty, easist way to do it. Go ask a local inspection shop, haha.

stephen · April 22nd, 2008, 11:54 AM

At least in Calif. it's against the law to remove a catalytic convertor from a car.

If one is removed because it's defective, paperwork has to be submitted justifying the replacement, and the old one has to be retained for a period of time, in case it needs to be inspected to confirm the reason for removing it.

I don't think it is a good idea to remove the convertors.
