My gc8 with a built 207 in it pulled 310kw on the Dyno. It’s quick!

[@PossumBourneMotorsport]

310kw would make for a rapid GC8!

[@GIXXRBRAH750]

I have an opportunity to own a v5 sti bare block with heads I wanna run my bugeye Wrx intake manifold or some bugeye sti intake manifolds and build it … it’ll be a direct bolt on with everything won’t it

Does "straight pipe" mean no mufflers, cats or resonators?

[@PossumBourneMotorsport]

Yes exactly! It's essentially a 'Straight pipe' from the back of the turbo to the end of the exhaust. It was damn loud!

[@Jdm02.nz.]

@@PossumBourneMotorsport so illegal in new zealand then? you built an illegal exhaust system for "Fatu" to run into cops as soon as he gets onto the road 😂

[@PossumBourneMotorsport]

@@Jdm02.nz. this is going back a while - but I believe we built the system so it had an interchangeable rear section. He could run it straight pipes at the drags/track days etc, or fit the muffler for street driving.

[@model876]

any info on that ewg setup? never seen anything like that in the US

[@PossumBourneMotorsport]

It’s a JDM twin scroll header that’s had a 90 degree stainless pipe welded to each of the two runners. These are then merged, with a divider to keep the gas flow of the two runners seperate whilst using a single 40mm turbosmart wastegate

[@model876]

@@PossumBourneMotorsport thanks for the reply! That is very interesting. I have been thinking about how i would go about doing an ewg setup on my ej207 engine. This is something i will have to put some thought into!

[@melissamares-salinas9465]

Very common in us bro

How much for a build like This? Roughly?

[@PossumBourneMotorsport]

Hey SPLIKIT, there’s a stack of variables, and weve made some advances in our R&D since this car was built. Drop us a message on Facebook or email [e-mail] and reference “Sleeper STI GRB” for more pricing info. Cheers

@@PossumBourneMotorsport awsome thanks!

[@avishkowalmungree1295]

Custom uppipe ?

[@PossumBourneMotorsport]

Still a stock STI Twin Scroll Up pipe

[@brookejones2540]

Is it legal to be that loud

[@PossumBourneMotorsport]

This car has an off road set up without mufflers. To meet Wof standards a muffler is required.

[@brookejones2540]

What turbo do these come with stock and gow much hp

[@oldfashionedwrx3574]

Is it really a sleeper haha

[@vaskodimoski5690]

Sounds like crap all that pop and crack should put a descent exhaust on it straight pipe cheap and nasty

[@PossumBourneMotorsport]

The owner has since decided to add a couple of good quality mufflers to the system. It sounds much more respectable and a lot quieter now :)

[@tellyawhatmate]

Much better, being a sleeper u wanna fly under the radar
