    The Nooob With the Scoooob, & 06 WRX Emissions question.

    Howdy Fellas!

    I've been in CO for a year now for work. Just recently bought a beautiful 06 WRX from Miami, FL. My old 4runner passed emissions, But I'm pretty sure this suby will not. I'm new to the tree hugging emission regs, hehe. My Temp tag runs out on the 9th of Nov

    ::RAMBLING:::WARNING::::RAMBLING:::::WARNING

    The upgrades I know of;
    -STI Turbo
    -3" Cat back (not sure what brand)
    -Bigger fuel injectors
    -A tune (FOR 93 OCTANE IN MIAMI!!!) that's locked (EcuTek?) and stopping me from tuning for Colorado

    MY CONCERN;

    I've read that the Cat in the up-pipe was ditched in the 06+ model WRX. I called a local guy who says he will put a stock up pipe in for $200 to pass, then come back to remove. I don't know if it's that simple though. I read the up pipe in the 06 doesn't have a cat!

    My main question is, Can I just buy a 3" universal hi-flo Cat, Have it welded on, & pass emissions??? I would rather do this than go to the shop mentioned above.

    Any advice appreciated, you fellas have some beautiful cars.. Can't wait to get involved & learn more about my new ride!!

    Thanks,
    Jon

    welcome.

    i know absolutely nothing about emissions since i'm in FL, but how can they fail you for not having a catted uppipe even though its like that from the factory? are you sure you didnt fail your inspection due to a catless downpipe?

    06+ do not have catted uppipes from the factory. You wouldn't fail for that. As Dez said it is most likely for not having a catted downpipe.

    How do they test cars in Colorado? Here in Tennessee they just run an OBD2 scan. I'm guessing you guys are getting a sniffer test as well.

    You keep saying "fellas" yet the first person to reply is a girl =P

    All the above is correct. 06+ lost the catted uppipe, you do not need to have it replaced. And 02-05 should have it removed as it only aids in cold start-up emissions.
    You will not pass emissions testing in CO with a high flow CAT, read:
    WARNING FOR BUYING CATTED DOWNPIPES!!!

    Your best bet is to get rid of the EcuTek(new ECU maybe), find a stock downpipe... scratch that. You have an upgraded turbo. Stock downpiple trick wont work for ya.... just find a shady smog test station pay the worker off in beer and hookers.

    Hmm... Wish I knew someone that lived in colorado... that would write about emissions equipment... That has a 430whp car that just passed emissions on pump gas... JaiOhIn. Give me a PM. If you want help figuring out what's going on, and you're near me, I'm more than happy to help you figure things out. It'd be easier to just look at the car in person, and see what's going on. I can also help you figure out what's aftermarket on your car. Because it looks like you have a lot more on there than you think.

    Also... feel free to read this (as posted above). I wrote it after a lot of research I had to do about emissions once I started getting over the top with my modifications.

    Thanks LADIES & Fellas.. for the replies! And yeah, I was a bit modest about the upgrades but I really don't know exactly what all was done because the first owner did it all :/. The guy I got it from said it would walk away from stock 06-07 STI's all day. Also, I blew the clutch the 2nd day and had stage 2 put in .. Dan.. PMing you right about...MEOW. And I don't understand up & down pipe exactly.. I know one comes off the turbo and goes... Down.. hahaha.. Thanks again all! Hopefully Danny can help me out!

    Or Sinister... Not you Dan, Ooopsy

    Here's a handy diagram to help out with the "what's where" question.



    If Sinister can meet up with you, he'll be able to tell you a lot about your car from looking at it in person. If that doesn't work out, I'd recommend taking some pics of the engine bay and exhaust under the car if possible and posting them up for the guys here to take a look at.
