ewg?

**Chance1218** · 12-09-2012 11:47 AM

Hey guys. So I figured that since no dealership in western Washington wants to sell a 2007 STi for less than $28500 I am going to make a champ of my wrx. I have a Cobb ap now and my next mods are going to be a Nameless Performance Turboback, Perrin turbo inlet, Perrin turbo thermal blanket + Perrin turbo heatshield, and the Grimmspeed crosspipe/uppipe.. I plan on getting ceramic gs parts plus thermalwrap for the cross/up/down pipes...
But I was reading about the ewg and I'm curious.. for my (so far) low hp mods, would that be worth it? Especially since the nameless dp is DWG..
I haven't really looked at many ewg parts, but I did see a Cobb ewg/tial 44mm at rsd.

I know I would need a tune for ewg which I would go to PIA in Tacoma.

I would get a different (bellmouth) downpipe if you plan to go EWG...

The only reason to replace your uppipe at all would be if you're going EWG. 2006+ WRXs have catless uppipes from the factory, there really isn't much reason to replace yours unless you're going EWG.

It would definitely be beneficial, but there are considerations:
*Parts cost alone = ~$500
*Will require a tune, as you said. I'd pick a tuner who is specifically familiar with EWG setups. I don't know about PIA, but I know PRE and Cobb Surgeline in Portland are familiar with tuning them.
*Full throttle is loud. You're essentially creating a boost-controlled straight pipe exhaust cut-out. It will wail like a banchee.
*Emissions inspections could be especially problematic, depending on the requirements. I know in Oregon, you can easily get away with downpipes and the like, not so sure about EWG. WA may be different.

hmm ok. still researching if the ewg would be a no-no in liberal washington. lol..
I know that it's 99% marketing and butt-dyno's for the most part, but why is it that people who get the GS cross/uppipes, say they get gains out of it?

I wouldn't do it.

Look at my build thread. It was a waste of money, a ton of fun, and I lost all that money. I got lucky and was able to sell my WRX over retail.... but the amount of money I spent was not worth the end result. I could have purchased a R35 GT-R for all of the money I spent on my car.

Not to derail the thread too much, but what's your plan now, Kevin?

EDIT: Nevermind. SRT8, huh?

Was going to... but I ended up with a 2013 Jeep JKU Oscar Mike. I'll post pics in my build thread!

Persons gotta have hobbies.. I made out great on my modified wrx

Lol well you also had a brand new motor and everything.. I am definitely not going that far. haha.. but ya im starting to turn away from the EWG for now.. maybe just turboback, Turbo inlet, and some nice Whiteline/Kartboy parts.

**Sinister** · 12-09-2012 06:59 PM

don't even do the turbo inlet. It's a difficult mod, and a pain in the butt for no gains.

Turboback is good... maybe a 3port EBCS... and a tune. That'll make your car a lot more fun

**careercadaver** · 12-09-2012 08:02 PM

The Perrin Inlet took about 30 minutes...

**Chance1218** · 12-09-2012 08:10 PM

ok so I know you guys said that the uppipe is useless unless it is EWG, but I was looking, and to keep "emissions" happy or w/e, I was looking at the Grimmspeed PnP Headers, crosspipe, and uppipe. All ceramic coated, then heat wrapped. Along with the Nameless Turboback, with the DP heatwrapped too. oh and the Perrin Turbo blanket and Heatshield?

An uppipe isn't useless, but the annoying install isn't worth it without it being an EWG or if you're doing a turbo swap (where you just have the two exhaust manifold bolts to replace it).

Go with a set of EL headers or leave the exhaust manifold alone.

The downpipe wrap shouldn't go past where it bends under the firewall; any further is wasted money.

Just cut your stock heat shield. Aftermarket ones look pretty, but don't function any better.
