• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

and let me clearify for the few children ha.....people who are not running the catalytic converter on their car.....Im looking into headers and i can get a deal on catless i was curious on how you guys that have echeck how your gettin passed it
 


I dont have any emissions testing here. You can have the codes tuned out and not have to worry about it.
 
OBDII check?

If so, could you not simply turn the codes off? The OBD readiness will jump to "READY" if you do.
 


we got the computer hook up, i pass its just tuned out in the computer. if you have visual just buy those "look like cats but actually just a straight tube"
 
yeah i know newer cars they just hook up to the computer but i have seen some get checked but hell might just take the cat thats coming out take the sheel off and weld it over the ehxaust they wont know the difference
 
My cat is gutted. No engine light as of yet.. I'm in MI no emissions testing here

jersey stopped doing the sniff test, but does the obd2 scan and a visual exhaust inspection for the car, they put these nice cameras in the floor as the car drives over it the tech can see the monitor. and its full color!

they also test the gas cap.

and its every 2 years as well now.

Heat gun will give it away.
 
yeah i was thinking of making a fake one idk but here in ohio they just started the self serve echeck via the obd2 so maybe i can get away with the cumputer trick

Simulator will kill the SES light but only screw with the cat diagnostics in the PCM if it is an '01-'08 car.

'97-'00 you can use the sim and it works.

Otherwise, get a fake cat from frozen boost.

I removed mine on my 99... no codes besides switching once a week. Best way is to tune it out, but if you have to pass a visual inspection get the headers for now and save for a high flow cat. Looks proper but flows much better and most of them won't set off a code when used. They are a little costly tho, but the biggest thing is how are the inspections done in your area?

Why get a cat at all?
 
I gutted the factory cat, welded a through pipe, and installed a simulator. Although we have no testing, it will still pass visual and OBD tests. A note, whatever the cat is made of, it's a pain to weld.
