FMIC or downpipe?
I currently have buschur catback, ur testpipe and uicp, and ets intake. Due to some unforseen circumstances, the next mod i get will probably be the last one for a while. I'm trying to decided between a FMIC or a downpipe/02 housing. I've compared prices but need more info on the difficulty of installing the downpipe, and people's opinions on whether i should get the pipe or the fmic. I also plan on getting it tuned soon after i install whichever one i end up getting. Thanks in advance for the opinions.

ease of install = FMIC
Power gains, probably go to the intercooler as well.
The o2 housing is a ***** to install and if you aren't comfortable with tools and your car its probably not the part you want to buy.
When i installed my FMIC i felt an immediate gain, most likely not due to cooling probably due to how well it flows. I got the AMS and i highly recommend it.

I'd say the FMIC from the point of view that even if it doesn't increase power very much, it will give more consistent power delivery since it will not heat soak like the stock unit.

Xtreme boost. AMS's test was done only on the downpipe portion, and didn't include testing on an o2 housing. Xtreme boost's downpipe/o2 w/ open dump combo yielded 30whp vs using the stock downpipe/o2 housing.

How does a FMIC make more power?
Your next mod on the list should without a doubt be the downpipe. On a hot day you might see the benefit of an upgraded FMIC but there's simply no point at this level. Right now you're getting the most restriction from your stock downpipe.
An upgraded FMIC is almost last on the list before you upgrade your turbo. Many more mods make better sense long before the FMIC.
That's just my 2 cents...

From what I have read, all test yielding no results were with just the dp. Test where the dp, and o2 combo were done yielded power, and according to Ultimate Racing it is not cost effective to just make an o2 housing, so they make they o2, and dp as one piece.

I would go with the FMIC as well. There are still 02/DP pieces in development and it would benefit to wait a bit to see what everyone has to offer. Right now, pretty much all companies have a FMIC out, so you get a broader selection.

Go with the front mount. The factory downpipe is 2.75", mandrel bent, and flows very well. The factory intercooler DOES heat soak easily. An upgraded intercooler will beneficial at this time, allowing denser, cooler air to enter the intake manifold. More boost, more timing, more POWER!
P.S. You'd be surprised what a dremel and some time will do to your oem o2 housing
