Turbo Problem .... smogcheck fail?
failed my idle part of smog check but passed my 2500 par. I got an APR chip, Downpipes, bipipe and exhaust. do i have turbo trouble or is it just the apr downpipes w/ all the upgrades?
i am stage 2+ except for intercoolers and snubmount
thx for the help guys, nothing worst than a visit from the turbo lady.
by the way your allowed to have 100 HC(PPM) in california but i had 194!!!!!!

Do you have CATs with those APR DPs?
that'd cause you to fail smog check.
or did you fail based on physical inspection?
Any aftermarket exhaust can cause a fail - depending on if they are busting oyur nutz

IIRC, the "test" pipes are straight - so you must have cats.
I'm not sure how many CEL they are, so you might want to search to find out if anyone else is failing emissions with the APR DPs.

in theory, they should....the next question is
1) Was the car NICE AND WARMED UP? if it was cold, those race cats might not cut it
2) have you had any CEL as a result of running those DPs?
3) considered any other problems?

These are the old APR downpipes. The cats are shown at the top and bottom in this image. From your description of "REALLY small" cats, it almost sounds like your confusing the flex joint with a cat. The test pipes are shown in this image directly inline with the downpipes.<ul><li><a href="https://forums.audiworld.com/s4/msgs/1232514.phtml">Mark P's APR downpipe post</a></li></ul>

CEL = Check Engine Light (and a code that would indicate...
the CATs aren't doing their job)
Ask K04Madness what that code is....he runs test pipes and gets CEL all the time.
