ok - here is the question...... how can emissions tell that i have an after market Y-pipe.....i mean...... the stock Y pipe doesnt really look that much different from the aftermarket.......does it??.......are the emission guys really that smart?? ( i didnt get the pipe yet.....but i really want one)

 

well, I doubt he would really crawl under the car to check for pre cats. when I went to get smoged, all he did was a quick peek under just to see the main cat converter.

 

After-market y-pipes usually do away with the pre-cats.

With a cold engine, you'll fail emissions. Make sure you warm up your car, and drive it around for a little while until the engine is running at normal temps. You should pass with no problems.

(You should have noticed that your exhaust smells rather 'rich' with a cold engine)


OZONE KILLER!!!!!!!!!!!!!!!!!!!! DIE DIE ..... j/k

 

Thought I'll add a little. Pre-cats are there to reduce emissions until the engine is warm and the cat does its job right.

So as long as you don't go for your emission test with a cold engine, you'll be fine.



BTW, I'm promoting "Search is your best friend" today ....

 

oic - i just hope my next emissions appointment isnt in the winter!! - that wood really suck!

 

I don't think winter would matter a whole lot. As long as your engine is warm, and you've driven it for a while. Someone back me up on this, coz I:
a) don't have a y-pipe (I love the ozone )
b) don't need to do emissions (Michigan)

 

Pre-cats would not be at issue. Many cars do not even have them. What they will notice is that the front exhaust pipe is newer than the rest of the exhaust. You can always say that your old pipe had a leak or rusted out and needed to be replaced. As for the emissions part, that is still largely dependant on the CAT so if you have an aftermarket Y-pipe, you warmed your car up before testing, and still failed, it may be time to replace the bugger.

 

You shouldnt have a problem. Unless you live in a smog restricted state where they are really hard and they check emmisions really closly. Here in NJ all they do is peek under with a little mirror to see if anything has been changed. If you go when its busy here, you can get away with having no cat too ...

 

lol - how about if i like splash mud or sumthing onto the Y pipe and make it look older

 

lol or spray some rust-colored paint on it


what sucked when I had to smog was I had to wait in the parking lot for almost an hour for my turn to smog so it had time for the car to cool down and thats why I failed the 1st time. good thing they allow 2 chances for you to pass so I took it up to the freeway to heat it up again and this time I left it at idle while I waited in line again and passed 100%

 

ahhaah - rust colored paint.......anyone from new york city have any problems?

 

Of all the times I've taken cars to be inspected, I have never once had anyone look under the car. Now, with the new test, why bother? If it passes on the dyno, who cares?

 

yeah......but yor in a completely different state......that may be the reason =)

 

Hehehe! I just put my Y pipe on today...works sweet! My advice to anyone who wants to put on a Y pipe themselves is as follows:

1. spray on WD 40 onto ALL the nuts and bolts (8 nuts 2 bolts) preferably the day before you do the job.
2. Use impact sockets (hexagonal) and get extensions and universal joints. The back nuts are difficult to reach because of all the precat crap.
3. Get an monkey wrench...useful for removing the front oxygen sensor
4. Replace all gaskets
5. Use high temp gasket sealer. (muffler shops I've been to do)
6. Use anti-seize on the oxygen sensors when you put them back in.
7. Tape up your oxygen sensors while they're out - they're easy to damage.

I found it easiest to put the front pipe up first and then the back joint with nuts loosely holding the pipe, then wiggle the center into place and push up..

The job takes only 1/2 hour to 45 minutes....piece of cake if you don't round off some nuts...like I did . If you do, you'll need to heat them up with a welding torch.....use IMPACT socket!

Just thought I'd share my experience.

 

Hehe I just passed my emissions before I made the change...so don't need to worry about that for a while.... Should stil pass if the engine is warm though

 

be worried if they do look and see that nice big "for off road use only" plate

 

Not on a Budget pipe

 

hehehe - i got a real nice budget pipe........ one side is a highlighter and the other side is a bong .....well its not budget.....but its umm.....KOOL!

 

well ok then, fine, if we must be picky

 

Not on Cattman either -- I think it's only on Stillen's.

Nismo: Did you have the Y Pipe and the Cat when you first failed?

 

I had: Y Pipe, Stock cat, stock b-pipes, stillen muffler

I failed the 1st time but passed the 2nd time when I went to drive around town again to get it all nice and hot.

 

I have a Budget pipe ! ... just felt like letting you all know... hehehe . its just a black pipe with a silver flex section. very inconspicuous (spelling?)

 

whats the deal with this budget pipe??? why do the manufacturers even bother writing "off road use only" - it just makes their overhead cost higher......

 

Think lawsuit, then you'll understand

DW

 

My budget pipe doesnt say anything on it ... it says "ive been painted black"

 

really? well the stillen was the only one i was sure of
