Features & Product Details

An External Wastegate (EWG) allows exhaust gases to be diverted prior to entering the turbo; thus creating a quicker turbo spool. GrimmSpeed's EWG has a larger diameter than the stock internal wastegate; this allows the exhaust gas to be released faster, which improves boost control, maintains maximum boost longer in the rpm range, and extends the life of the turbo. Moving the wastegate out of the turbo relieves the turbo from the massive amounts of turbulence that the stock internal wastegate creates.

The EWG Up-Pipe is built from 304 SS with thick 12mm 304 SS flanges that will not warp. The flanges have been CNC cut for perfect tolerances(no laser cutting here!). A flex section has been added; this will extend the life of the product(allows expansion/contraction of pipe without cracking) and will lead to less exhaust leaks. Users should expect gains in the 15-40hp range when tuned for the EWG set-up. Additionally, it will come ceramic coated in a black finish for extra protection against heat and corrosion. 

Package Contents:
EWG Up Pipe
Dump Tube
5 Studs for Up Pipe
2 Bolts, Washers, & Nuts

This includes all the gaskets necessary for installation.

This uppipe is not suitable for RHD cars.

Awesome :D 2 years ago

Defiantly the best up pipe out there! Everything looked great ecspecially the Cermanic coating. Fitment was perfect and was super easy to install (My motor was out so yeah) I would defiantly recommend the 44mm Ewg dump tube setup as well ;)

Amazing quality from GS as always. 3 years ago

Every time i order a product from Grimmspeed i know what quality i am getting. This up pipe was no exception. Solid and smooth welds with thick piping. The ONLY complaint i have isn't about the product. When installing this up pipe with a 44MM waste gate on my 2015 STI the power steering lines were a bit of a pain to move the waste gate around while worrying about the stock down pipe not getting in the way of the dump tube. Since i kept my stock downpipes what i had to do was cut the heat shielding off and heat wrap it.

Fitment issues 6 years ago

When we installed this we noticed the studs didn't line up with the turbo. We tried the stock Up-Pipe studs to no avail. At that point we took out one (1) of the studs and attached it to the turbo then fed the extra stud through the top to the bottom and tightened it up. It made a 5 minute job into a 2 hour job purely because the stud holes were either drilled in the wrong spot or drilled on an incorrect angle. Other than that the part is good quality and has been working fine for the last month. I would recommend this part to my friends.

QUESTIONS & ANSWERS

  • Q: Fitment  eddiebor157133 years ago

    Will this fit a 2002 WRX?
    • 0 of 0 people found the following answer helpful

      A:  While this uppipe would likely bolt up to your car, we are unable to confirm fitment as it removes factory emissions equipment.

      A:  When you buy the actual wastegate it should come with all hardware necessary to mount it to the pipe. Mike
