WHAT IS IT?

An external wastegate allows the exhaust gases to be diverted prior to entering the turbo. Dumping the exhaust gas prior to the turbo helps with boost control, maintains boost longer in the rpm range, and extends the life of your turbo. Our pipe is fully built stainless steel EWG Up pipe and stainless steel dump tube for turbo Subarus. Monster thick SS flanges that will not warp. We have added a flex section which extends the life of the product and will lead to less exhaust leaks
because the pipe can flex vs. warping the flanges in a non-flex setup(inturn creating leaks).


WHY DO YOU NEED IT?
Reason for switching to an EWG setup includes:

:) Quicker turbo spool by allowing the exhaust gas to exit pre-turbo. There is alot of turbulence in the stock turbo at the internal wastegate so by moving the wastegate out of the turbo you get rid of this nasty turbulence thus improving the effiecency of the turbo as well.
:) More efficient wastegate design that has a bigger diameter than stock allowing for the exhaust gas to be released quicker.
:) Hold peak boost longer. This allows you to run a lower peak boost and increase HP at the same time.
:) Much larger than the stock internal wastegate
:) No more boost creep...EVER!


GAINS?
Users should expect gains in the 15-40hp range when tuned for the EWG setup.



Another unique aspect of our package is that we include a bracket that holds your stock internal wastegate shut. This is great because you will no longer have to weld your turbo door shut which means you have no chance for leaks and you can revert back to stock anytime you want with no hassle.

if u rele want u can just have it welded back into the down pipe, i think ultimate racing or some other companys gt35r race turbo kit has the ewg routed back into the d/p

imo selling a quality prefab'd ewg setup that routes back into the dp is almost impossible to do. there are so many variables that change the location of the up pipe, turbo, downpipe, dump tube that its pretty hard to mass produce one. your best bet imo would be to have a local shop make one while its on our car/turbo/upipe. or you could step up and enjoy the atmo noise ;)
