I had no problem keeping my ewg closed on a td04 wrx with a .9 bar spring. If your wastegate is preloaded properly you shouldn't hear it unless you're above 8 + psi if you don't have a boost controlling device.
Not saying it isn't loud but if a cop hears it in town you prob deserved a ticket for driving obnoxious
ly. Know what I'm gettin at ?
Buuut I totally understand the noise paranoia .. cams no cat, ti exhaust = noise

With a dump the rest of the car can be quieter and the cop wont know it was you when you get off it and cruise by with a stock sounding car. The loud *** 3.5" exhaust with no cats and straight through little muffler car will be pulled over 10x as much.

im surprised the poster 10 or so posts up didnt see any gains going from recirc to dumped.
we had a local years ago, test recirc (at a mellow entry angle) v. dumped and gained 50hp w/ it dumped.
im sure modlist, efficiency, how close to being maxed the setup is, etc. play a role, but id expect to see some type of notable gain w/ a dump.

Just got my o2 dump on the car last night. All I can say is I am in love. The o2 dump and the FP anti surge cover, makes you car seem like it has a huge aftermarket turbo. The sound just make the car for me. It just make me want to boost everywhere.
Also fantastic product. Build quality is awesome. It looks like a lot of time and effort was put into the design. The only part that I had that rubs a little is my AC line. I just needed to adjust it a little out of the way and all is well. I also have an Aluminum Radiator, and perfect fit with that, no clearance issues.
I will put some pics up tonight or tomorrow.

I wonder if this mod would also help me gain some more power on pump.
Will there be as big of a difference from your (ER) built 2.0 with an Invidia O2 housing to an O2 dump?

if you dont mind the sound then definitely get the dump.. its well worth it. gains you see depend on your current mods tho. the sound is probably similar anyways with and without.. these cars cant be quiet unless the exhaust is restricted to hell anyways. even my cobb is loud wot and that was supposed to be one of the quietest exhausts on the market

99% of the time an o2 dump always outperforms a standard o2 housing. remember turbo cars don't want any backpressure after the turbo so when you open that exhaust up you get better throttle response, spool, and more power in general most the time.

Whose O2 should I be looking at? MAP / JMFAB / ToxicFab ?

I'm all for performance, I was just curious as Collin's O2 housing looks amazing. I'd be surprised if it didn't perform as well.
