Sounds nice, what is your exhaust setup?

[GMooreFan1]

There's only a Prodrive axleback muffler on it.

[sleepyweasel42]

Sounds excellent for just that. Good choices on the suspension work before more power!

Get that stock up-pipe the hell outta there! No need for a third cat! :D That's what the next project for my 04 WRX is. (I think!)

I'm too lazy in that I wouldn't want to bother with it when the car has to get smogged. California FTL.

[sleepyweasel42]

Damn. Here in Mass, it's all on CEL codes, so if you have none, you pass. The car's computer reads the smog levels.

So you can't even switch out your mid-pipe for a high-flow cat system? Do ALL the CA tuned subarus I see online really switch everything back out every year to get inspected?

[GMooreFan1]

@sleepyweasel42 Yes and yes. Although some say doing what you ask in the first question may be doable. It may depend on who smog tests the vehicle. Most people switch their exhausts back to stock for smog testing.

nice

[GMooreFan1]

Nope. AccessPORT Stage 1. JDM STI springs. Koni strut inserts. Prodrive muffler. Subaru 4-pot/2-pot brakes. Goodridge stainless steel brake lines.

Is she stock?

[GMooreFan1]

It has a regular 2.0L EJ205 flat-4 motor.
