    Looking at the up pipe will provide a better answer than someone like me could give you over the internet... but for what it's worth, my answer is "yes."

    Does anyone have any suggestions on which up pipe to go with? I would of course like to get the best while spending the least . I think I will go with the kind that does NOT include the EGT bung, and I will do the resistor mod. If I'm looking to upgrade my DP later and probably get a cat-back exhaust, what do I need to look for to make sure all of my pieces go together smoothly?

    Check out this thread I started a couple weeks ago. What is the best catless uppipe for a 2002 WRX?

    Rallysportdirect.com sells the ceramic coated bungless uppipe for $175.99 and the same one on GrimmSpeed's website is $179.99 + $24.99 for ceramic coating. Don't know how they can sell it for cheaper than the manufacturer but I bought it and am very happy with the quality. This part will work great with a new catless downpipe. It bolts to the turbo so it doesn't really affect fitment of pieces after the turbo. ***If you replace the downpipe you will need a tune***

    Glad to hear some girls aren't afraid to work on their car.

    Yeah... I bought my cermamic coated GS uppipe from RSD, and the bolt pattern was incorrect. I had to widen the bolt hole on the turbo flange with a dremel tool. Ask STI_KLR if you don't believe it lol

    Thanks. Project is going to have to wait. I can't seem to get the damn thing running right. I kind of need a neutral starting point before I can do cool stuff to it

    It's linked to in the Exhaust FAQ (which is stickied) - that's how I always find it if I need to reference it.

    I realize that you should be ok for emissions tests if the uppipe is replaced. What about if the uppipe, midpipe and downpipe are changed? That all have cat convert right? Would it still be possible to pass emissions? Or would I want to keep my stock parts and install them specifically for the emissions test?

    Depends on your area.

    I would.

    Yes, it will pass emissions in California with a catless uppipe.

    Uppipe FAQ: Read if you are thinking of buying one! - NASIOC
    What about emissions problems like emissions tests and legality? The main purpose of the uppipe cat is to keep cold start emissions low until the main catalytic converters warm up. Using a catless uppipe is a violatation of section 203 of the Clean Air Act. Each state has statutes that cover this subject as well. There have been no know reported cases of catless uppipes causing state emissions test failures.

    It should not pass emissions in CA. In fact the car should not pass emissions anywhere in the US. It may pass emissions in CA. I've had my car smogged twice; it would not have passed the first time, as the guy knew his job and knew where to look. It would have passed the second time provided a resistor fix prevented a CEL.

    So the upside on doing this is to protect the turbo and gain a few hp. The downside you wont pass smog?

    You should not pass smog. I purposely made that distinction.
