uppipe. adds more power than a downpipe, cheaper than the downpipe. If you get the downpipe first, you'll have to remove it to install the uppipe (not a big deal but it has to be done)

Doesn't the downpipe add more power?

used oem uppipe on ebay $30.00. Then gut the sucker. then get a reasonably priced dp, like stromung, bosal and do the install at the same time you put in the gutted uppipe. the uppipe is much more labor intensive...might as well do both as dohcammin said. good luck! oh yeah, then scrape together another $600 for the acessport so you can kill any cels and have the ecu tuned to your mods. take note, this is not gonna be a cheap hobby! but you will have one fast motha.

Buying an uppipe is cheaper than buying a decent downpipe, if you do your own work (or have friends that will). But an uppipe + labor is more than a downpipe + labor in most cases. Poerwise, you'll see slightly bigger gains with the downpipe, but it won't spool as fast as doing the uppipe would. Either option will make more power and spool faster than what you have now however.

I would also have to say, save your money and do both at the same time. As most people have said, the downpipe will give you more power, while the uppipe will provide quicker spool. Personally, I have the helix up/down pipes, great fit and finish and gruppe-s provides a cel fix with the downpipe. If you can do the install yourself or find someone to help it will save you mucho dinero, since install of the uppipe takes quite some time, but really isn't that difficult. That was the first thing I did on my car and it took me 1 weekend.
I would go with downpipe first. Cobb posted at their forums that the uppipe doesn't really see big gains which is why their stage 2 doesn't require it.. usually around 6-8hp but like many say... you do get faster spool.
With a Catless Downpipe and a good Axle back tied to it... usually people see +15-20hp, faster spool and the option to flash to a Stage 2 Cobb ECU.
So get the downpipe if your limited to just one

i wonder what cobb will be saying about uppipe gains now that they are comming out with a sweet uppipe? i still think gutting the sucker is the way to go......more money for accessport, downpipe, shortshifter, sway bars, alpine stereo, yadda, yadda, yadda

about the downpipe first idea...isnt there some rumor about the cat in the uppipe breaking apart and sucking into the turbo? I just went the safe route and bought the up/down at the same time.
heix up/down combo was on sale for less than $500 from www.gruppe-s.com

well after gutting an uppipe i can tell you the chances of the cat breaking apart are slim to none. took me hours with bf hammer, drill, dremmel, bent screwdriver....it's got some serious stayin' power....probably last a hundred years if some ahole kid didn't tear it apart. now the egt sensor....that's a different kettle of fish, this is the thing that could screw up your turbo...it's why most aftermarkets come with a bung. for those interested http://webpages.charter.net/baraboo_...ppipe_fix.html enjoy!
i agree with the gutted up pipe and then buy a good dp and ask for help installing in your local community..im sure if you through some food+ drink people would help you out.
