Default 2012 WRX stage 2 questions

I'm currently running stage 1 TP but interested in stage 2.

If I understand correcrly, stage 2 is just downpipe and tune? Are there any downpipes that bolt up to stock exhaust?

Do you guys have to start upgrading trans parts such as clutch with stage 2?

Any issues you have experienced?

Yes. Yes .

No

Can't speak to issues as I don't have my car yet but if you search the forums you can find many posts that can help you out. Try searching next time. You're welcome.

I've heard there's any adapter you can buy to make it for right. But why not just get an exhaust ? Look at Invidia stuff. Also if you don't drive terribly yours trans will be fine. I'm stage 2 on my 02 wrx(weakest 5 speed) and nothing's gone wrong...just drive it nicely.

Okai, so

DP and Tune, you are correct.

Yes Cobb DP will fit to stock exhaust, I have a cobb dp to my 2011 wrx exhaust.

I wouldnt know I have a 4EAT but I believe you wouldnt have too.

Issues? Once, But it's easily cleared with the AP. Its the p2096. Rear O2 sensor, it's pretty common for turboback exhaust (once you get that dp). Does nothing, just freaks out at the air. It will put you into the safe mode (cruise blinks and stuff), just pull over and clear it and be on your way. pretty normal. If it happens pretty frequent, than something is actually up. go check it out, could be a air leak from somewhere, like gaskets and such. Its not a mechanical issue as much as little things.

Most downpipes will mate to the stock catback. If the DP is 3" then you should probably get a 3" to 2.5" adapter (like the one made by Grimmspeed) to smooth the transition, other than that you just need a tune and you're on your way.

Since you have an access port, any catted downpipe will work with their off the shelf maps. Just put on the Invidia Q300 quad titanium tipped cat back on a friends 2013 yesterday. Holy hell it sounds amazing. And being that he has a 2013, the only brands that sell quad exhausts for the 2013 are Cobb and Invidia (from what we researched) and the Invidia looks better imo, cheaper, and it's louder. But not obnoxious loud or anything. You might be in the same situation with the 2012 but I could be wrong.

If you are going dp to stock catback though, I would say get that 3" to 2.5" adapter from Grimmspeed as eggroll said. Essentially at Stg 2 power, the catback pretty much just becomes an expensive noisemaker and won't be restrictive enough to cause significant losses to power from a tune.

So once you have a DP, just load the stg2 map w/ or w/o intake and what fuel you run =GET A TUNE, and you will be good to go.

EDIT: well that's embarrassing. I read stg1 AP.. not TP

If you want to run OTS stage 2 map on accessport than all you need is catted downpipe of your choice and map reflash. Catted dp supposed to prevent boost spikes. Most dp's are full 3" so you'll need adapter to mate to your stock 2.5" catback. Cobb dp tapers down to 2.5" so no adapter needed. If you talking about Pro-Tune stage 2 than you will benefit more with complete turbo back, cold air intake, external wastegate, fuel pump, injectors and intercooler. Above mentioned parts get expansive. Your transmission and clutch will be fine as long as you do not launch your car and do no crazy 4th to 2nd gear drops. At any stage 2 don't forget to get a quality catch can or aos like crawford.

Hmmm still not sure. My main thing is reliability over the long term. I understand adding performance parts decreases reliability but I'd rather not have to start upgrading trans parts and all that.

Is stage 2 a huge difference from stage 1?

Also, is it possible to get a dp or full exhaust that is pretty close to stock sound? I don't want something ridiculously loud.

Big difference from a stage 1. I was running a stage 2 setup on my 13' WRX hatchback with an invidia DP, night and day difference.

P.s. If you run a cat-less DP you will definitely need a custom tune. The OTS maps on my AP did not work well with the cat-less DP I had on the car however, the OTS maps work well with a catted DP.

I would run a catted DP.

If I am going to do it, my setup would be catted DP with TP stage 2 tune.

If reliability over the long term is your goal, i'd suggest getting an air/oil separator, or at least doing some reading into the merits of that upgrade.

Get a Cobb dp- bolts up to the stock cbe. Get a tune from Eric. Enjoy.

You might need a new bpv, and maybe do the bulletproof mod for the tmic. That's it though.

I don't think those are necessary for a simple DP upgrade with stage 2 map. He'll max out at 19psi. Your stock BPV should be fine at that pressure. Although it'll be nice to upgrade/mod the tmic I think it's also unecessary for what OP is planning on doing.

This greatly depends on the tune and how much you're enjoying the new power.

Mainly the latter of the two, but the tune does effect it. You'll get more MPG with a protune than with an OTS map... to generalize.
