Looking to go Stage 2... NEED HELP!!!

**atissasha** · 11-28-2012 06:55 PM

Hi All,

I bought my first 2012 wrx hatch in wrb and currently have a Cobb AP, Turbo XS BOV, and an AEM CAI, stock exhaust.... It is tuned with the Cobb stage 1 93 octane+aem...

I am looking to go stage 2. What is the procces? What will have to be installed other than a down pipe and could I do it myself? And how much power will I suspect to gain... Any recommended downpipes?

Will the stock exhaust sounds louder with a down pipe?

Thanks!

Just throw the down pipe on its not to hard at all and get rid of the BOV , flash stage 2 on there just like u did stg1 on your accesport , and enjoy. The exhaust will be a Lil louder with an after market DP but not to bad . Get a TBE if your looking for it to be a lot louder

What is a TBE? And what Downpipes do you recommend?

Please, please, please read the stickies! Everything has been broken down for you and discussed to death in other threads. I'm sorry, but these sort of threads make me want to Hulk smash a puppy.

Here, check out this thread, it will get you started. First Modifications - what to do and not to do

Then, please search! You have an AP, so what does COBB say you need? They don't exactly hide that information.

TBE is a turbo back exhaust ,
Cobb and invidia make really good down pipes as well as TBE's

Cobb outlines the requirements for each of the maps they offer in their map notes; follow them. They also list the gains.

Hi man!

Here is a very detailed how to tutorial for an already simple job.

DIY Stage 2+ (Downpipe, Uppipe, TMIC, EBCS, Ram Intake, Wastegate Blockoff, EWG)

You will need a downpipe and like others have recommended Invidia is a great product. If you plan on using ots maps from Cobb I would recommend getting their catted one to help prevent over-boosting. That being said you may have problems over boosting till you get a tune.

Let us know if you need any parts and we would be happy to help.

Have a good day!

Make ire you hear wrap the s*** out of that Up Pipe I'd also recommend silicone coating it with DEI high temp silicone.

Or you could just get an STI Up Pipe and keep the OEM heat shields. You could likely sell that BOV and get an StI Up Pipe for little to no investment.

If you want more turbo noise do a silicone turbo inlet (I recommend Perrin as many other cave over time) a hard inlet may do the same but the Perrin was cake to install!

What would that accomplish? He wouldn't be able to run a S2 map with that...

This post killed way too many of my braincells. Those cells were supposed to live to die by alcohol consumption. But too late.

I meant the Uppipe as far as wrap and STI set-up...I was half asleep...

Ill correct my original post. I'd still wrap the DP though...with as many heat related issues to the number 3 cylinder and cv boots I'm surprised anyone would disagree with as much heat wrap as possible...

Why would he need an STIi uppipe? 2006+ wrx came with factory uppipes. Wake the **** up man, what Mikie said,... alcholol....alkolhol... alcolhol!

Is the Sti Uppipe not larger diameter? All I was saying was he could retain his heat shields that way as opposed to wrapping. I'm more familiar with the 2.0L so if that doesn't cross over to the 2.5L WRX my bad. A lot of the 2.0L wrx owners will run 2.5L STI Up Pipes.

The only difference is the catless pipe vs catted. Any of the 2.5L WRX engines have this, not just the STIs. If you have an aftermarket downpipe, you'll need to modify the stock turbo heat shield, or buy an aftermarket one.
