I need to order a new catalytic converter.. cuz i was dumb enough to put a test pipe on my car when i got a y-pipe and cat-back. Now i need to pass emissions. When i took my car in for the first test, the best i did was double the allowed levels not cool, cuz i want to not have my license plates suspended. So i need to pass this test, and i'm hoping that putting a stock cat on for the test should do the trick.

Firstly, is that the only thing probably causing me to fail so bad.. i'm sure it has a huge impact. My car runs well except for a rough idle due to the IACV. But are there other common things i should check for

Secondly, is there a site where i can find a stock cat for less than like 140 bucks. I hope so, otherwise i'm gonna be a little upset that we cut the old one to crap trying to get it off cuz it was so rusty.

 

Nissan cat for $140 wont happen, just order another one. Do you have any other codes?

 

i think to pass emissions with a y-pipe you have to allow the car to warm up first also

 

you smogged with a test pipe????

 

You can order a CarSound Cat for $100. http://www.warpspeedperformance.com/nissan.htm

 

what did you do with the original? Your best bet is to go to a local junk yard and find a low rust max and take one. Good luck getting a stock cat for anywhere near $140 anywhere else. I believe a new one lists at $1000

 

Make a thread in the for sale section, you might get lucky. Or Junkyard...low rust as suggested.

With an OEM cat and no other codes you should pass emission as the cat has materials in it that clean up the air comming out of the exhaust making it less pollutes than if it came out of the headers and straight to the outside air.

 

haha yes, i smogged with no cat.. knowing full well that i would fail. But that gives me 3 more months to get it fixed. so thats ok

 

also, am i just confused as to what i'm looking at here.. but i've found a couple sites that list a "rear catalytic converter" for 1995 maximas for around 150 bucks. Tell me if i'm wrong

i'm hoping these would bolt on to my y-pipe and catback.. i don't see why they wouldnt. please tell me these work, and that what i'm looking for doesnt cost 1000 dollars as someone said up top.

 

hmm... unless the nissan engine is way different, my other car had no cat and barely failed emissions, then I put the cat on and failed again, No2 I think. Everything else was way below the maximum. So you probably need some sort of tune up, or just warming up the engine beforehand

 

$1000!!!??? u must of misslooked or something. i thought the OEM ypipes were around that.

saw some for around 140-150

 

i'm about to get 1 myself cause the CM's pipe suck. i talked to someone over at warpspeed and said theres is really close to stock so i might just grab one soon

 

get a hi flow from warpspeed for $100, if will pass smog, mine did.

 

i payed like 75 for my Catco and i passes too

 

is that your only regret about the test pipe...that it wont pass emissions...cuz i just had one custom made and im not usisng my O2 sensor at all(it is zip tied to a bracket) and i havent thrown a code yet...did u all with test pipes throw an o2 code??????????

 

in maine the sales of a used cat is illigal. so if its the same in your state good luck finding one at a bone yard. its possible to get one say under the table but they may charge out the azz with no warrenty. I have a carsound from WS, may as well buy new!

 

Guys, sorry if this is a retarded question-- but is there a link anywhere that would show ALL the components and their location of the exhaust system? Y-pipe, cat, etc. so I can kind of get a visual of all the pieces? I want to make sure I understand everything that is under there...

 

you can have mine if you pay for shipping (I gotta yank it out still) and hell, $10 for my trouble :P but I gotta yank it first (which means I gotta weld a bung to my new cat)
