Welcome, you didnt loose anything. Even with an after market intake you only gain 1-3 hp. For real hp increases look at a turbo back exhaust and engine management. Read up on boost spike/creep, you'll have those issues with your car if you put a downpipe on it. You may also upgrade to a better panel filter, should also increase the pssh noise level if thats what you were looking for. OR you can get a cobb sf intake or SPT. Both pricey but they just make noise.

You need to get a high-flow air filter (like K&N) to see the benefit of removing the air silencer. Even with that - you won't see much of a gain.

Welcome. Good work getting an 07. Same here with the intake silencer. I got bored one night and took it out, reset the ECU, waited a couple hundred miles and still definately lost a little power. Put it back on and it was back to normal. Now i have an AP so i don't mess with intake at all due to the BIG CAPSLOCK WARNING ABOUT STOCK INTAKE.

New intakes and blow-off-valves are religous debates (seemingly).. Some people love them, and others despise them. I personally still haven't sorted through the fact and fiction of the matter.

The TBE and ECU reflash putting you to stage II is a very commonly preferred mod though - most folks do it. However, I don't see how that can be in the same pricerange as an intake though.. The COBB AP is $645 alone, full stageII setup from COBB runs just under $1500.

The fact is in most cases BOV = is a less than helpful mod and the intake is a fancy noisemaker

I did not tell him to order cobb stagII i told him to replace his downpipe and flash stage 2 one is much cheaper and you get the same result with less noise.

Cobb would rather you did not do the intake mod on your 07 to run the ots maps,

The WRX does not need mods to be fun to drive, have fun and save money for the right mods.

engine management, no Electronic boost controls, no manual boost control, no BOV, these cars are sensitive to changes in the turbo systems, intake and exhaust, to do any real changes you need Engine management to allow the ECU to adjust for these mods

Mud flaps are a nice mod, my first cheap mod was a billet prodrive shift knob and satelite radio.
