How Much Gain Am I Gonna See?
i have ordered my first mods for my evo IX, they are as follows...SSautochrome Turboback exhaust (I know it comes with downpipe, but i want good fitment), Invidia Downpipe, Invidia O2 housing, Hallman Pro RX manual boost controller, Walbro 255lph Fuel Pump, Defi BF series Boost gauge, Defi Link Controller II, and hopefully very soon a solid reflash of my ECU. I just wanted to see some rough estimates on how much gain i should be expecting. thanks
i know a guy w/ similar mods laying down 360whp on a dynojet.
too bad u are using the invidia d/p and o2housing(well not really)i would like to see a dyno chart of this exhaust set up to see real results.
i had invidia exhaust on my wrx. flawless welds and great fitment, hope its the same for u.

Why did you get the invidia o2 housing? the ssautochrome one is $70 shipped on ebay and is a better product. Also, get the regular Hallman Pro instead of the RX.
Your not going to see hardly any gains w/o a tune and your car's not going to be running quite right. All those exhaust mods reduce back pressure and will more than likely cause your ECU to freak out and pull timing. I have a tbe (catless) and an o2 housing with no tune and my car doesnt like it, I havent logged it but Im sure Im knocking which causes the ECU to pull timing.

i got the invidia o2 housing and invidia downpipe together in a combo package, as I did with the boost gauge and boost controller.
That's too bad. The Invidia o2 is not recommended, especially if fitment is one of your main concerns.
As for estimates, please don't bench dyno. Put on the mods, get tuned, and go find out what it does at the track. If you dyno, then be sure to dyno before the mods so that you know exactly how much you gained.

Depends on a few things: assuming you're running a test pipe; mbc spiking to 24psi; and good tune - probably more like 330-340whp on the average Dynojet - overall, if I recall correctly, that would be a gain of around 80whp.
Most people on here recommend the Ebay/SS/Megan O2 housing, as it produced the most gains when Buschur dyno tested it...

The only fitment problem with the invidia o2 housing is the moves the o2 sensor to the front of the o2 housing and unless your an idiot there wont be a real problem its just a hassal, as for bolting it up there is no problem, i have a complete invidia turbo back and it fits perfect
