if your worried about passing emissions because of the visual inspections with your 3" catless dp. this is for you! just weld it in and go!

thought i would share with those who have never seen these!

3" straight pipe but looks like a catalytic converter!

 

lol now that is the ****.. haha...

 

lulz i love it.

 

Man... will i have problems running with no cat? I remember adding rubbing alcohol to my firebird to pass emissions... what about our cars? Sorry may be a stupid Q

 

without the catalytic converters you will FAIL EMISSIONS.

 

^^ not really....

 

well it isnt a visual test that is for sure...so this has no real use

 

depends where your located. but just throwing something on like the OP posted is your safest bet if all you have is a visual inspection.

 

get the rear o2 shut off .. and that "mock cat" and long as they dont do hardcore sniffers or anything you'll pass

 

exactly. i know a few people who inspect emissions in ct. they said they check for codes (cat efficiency codes) and do a visual to check that the cat is in place. so for me, i have my rear o2 tuned out, and i'm getting this so i will have no worries when emissions comes around

 

im in cali. i cant pass even with a high flow cat. i failed it so bad, i was about 1000points over what was expected. hahhaha.

 

bad tune maybe? or something else has been done? thats a really bad score... Do you know what you were over on?

 

cali dont **** around lmaoo

 

lol nope

 

ya we have those ******** to thank for the SAI system.......i love how NY just adopts their emission standards uber gay

 

Waste of money I dont know of anyone that just looks to see if you have a cat they hook up a sensor to the exhaust that tells them everything. i think the only way to pass without a cat is to know the person doing your emissions

 

Or you could just gut your cat and have the same **** for no more money...It is illegal for you to tamper with or remove a cat that isn't broken, so when they see this nice shiny piece of new exhaust in the middle of a rusty set of pipes they're gonna flag it anyway. Take a screw driver to your original cat if you want to do something like this.

 

a shitload of places do not do a sniff test.

i just talked to a guy i know who does emissions. they scan the car for codes to check if the post cat o2 is reading a converter problem. then they do a visual inspection to make sure there is a catalytic converter is in place

this would look normal welded into my 3" downpipe...considering its basically new and not rusty at all. i don't have my stock cat so i found this

and i found this for my brother because we have long tubes on his trans am and he has emissions in june.
