Default Starting Cobb Tuning Journey

Starting the Cobb tuning route on my '09 WRX. So far I've flashed the base 91 octane map, but plan on adding the Cobb DP and intake for the Stage 2+ map. (Already have the SPT exhaust)

Who else has gone this route, and what are your thoughts or suggestions?

Catless down pipe, EWG, and a Dyno tune. If you're staying at stage 2 get a dyno tune.

COBB= big name = big prices. Have fun with the AP it's a great product. Just remember you don't NEED all COBB parts for things to work. Example, I have invidia down/up pipe for half the cost of COBB and it runs perfect. Keep that in mind when you start putting a shopping cart together.

Why not? He asked for thoughts and suggestions.

Random suggestions?, or a person just starting on his build? An EWG is unnecessary for a stage 2 setup. Yeah it's cool to say ya got one, whatever. But I huge waste of money that can be donated to somethin else. Needs goals, a budget, and what you wanna do with the car, autox/track days.

I've gone that route before. It becomes quickly apparent that stage 2 is not enough power. o_0

I appreciate the input. From what I understand, the Cobb DP tapers down from 3" to 2.5" on the exhaust end to make it easier to bolt up to the factory exhaust. The Invidia, or most other options for that matter instead are just 3" all the way through. This leads me to a few questions:

Will the Invidia bolt up to the SPT exhaust using the donut gasket?

Will the airflow be close enough that the AP map will still work correctly?

Is there a better option for the ram air intake other than the Cobb?

Should I also look into getting a new UP, and what are the benefits, will this affect emissions if both cats are removed, will it still function with the AP, etc.

I know I can google much of this, but I like to get opinions from various people to get the pros/cons.

Screw the up pipe. Ours are catless anyways.

The Cobb sf is fine, even better the stock one is. But if ya dig the sound like I do of mine stick with it, Cobb has a specific map for the intake which is cool.

Your exhaust question, it doesn't matter. I'm almost positive the downpipe and catback will match of just fine (quality brands tend to stick to a strict fitment) with addition of a grimmspeed 3 to 2.5 adaptor. Great product. Your not looking to get any power with the smaller catback. Mainly gives you the sound you want.

I've read that a 3" exhaust isn't really required until you're pushing closer to 350hp. Is this really the case? Should I think about replacing the SPT in the near-term?

I was looking at some different DP options, and was wondering what the different was between the standard Invidia pipe and the dual bung Invidia pipe. According to the reviews the standard pipe had a better rating. What exactly is the dual bung for anyway?

Also, is there anyone from Washington that has had problems having emissions checked without a cat? Should I worry about getting a catted DP, and which would you recommend?

Are you planning on pushing 350 to the wheels? Instead of worrying about your exhaust at that point you'd be worry about your trans. I own an 06 (spirited driver but treat her right) I'm not clear if they upgraded the trans for your year, you should look into that if your planning on hittin 350.

The invidia is nice. Perfect fitment. Good quality downpipe. I went catless. Saved a couple hundred bucks and if your handy you can change them out yourself fairly quickly after you've done it a couple times. The dual bung is usually for a wideband gauge. Single bung is just for your o2.

Can you tell me what happens if your catless and why a EWG is beneficial in that case. Probably not because you are just another newb talking our your ass.

If you have an issue with boost creep that can't be controlled then yes you can use an EWG but let's wait til issue comes up.

There are no issues. He asked for suggestions so I gave one based on my experience with multiple stage 2 set ups.

Just curious, how much did you make with the EWG? I was just lookin through some threads Ed from EQ was tuning. A 2.0l tdo4 EWG, made 231/231. What numbers did you hit?
