Features & Product Details

This is the Grimmspeed External Wastegate 2-bolt Up Pipe Kit that features a 38/40mm external wastegate flange, and a Turbosmart Comp-Gate 40 External Wastegate. This setup allows owners to convert their internal gated setups to an external gated option. The benefit of an external wastegate is that it allows exhaust gases to be diverted prior to entering the turbo which will create a faster turbo spool. And because the external wastegate has a larger diameter than the stock internal wastegate, it allows the exhaust gases to be released faster which improves boost control, and it promotes longer life in the turbocharger. More importantly, moving the wastegate out of the turbocharger will relieve a large amount of turbulence that the stock internal wastegate will create.

Grimmspeed fabricated this up pipe from quality 304 stainless steel materials with thick 12mm flanges that will not warp. The flanges have been CNC cut for perfect tolerances and a flex section has been added to extend the lift of this up pipe, and it will allow for expansion and contraction without cracking, and it will lead to fewer exhaust leaks. With a good tune, users can expect gains of 15-40WHP when tuned for an external wastegate. 

This kit will include:

- Grimmspeed 2-bolt 38/40mm External Wastegate Up Pipe with Dump Tube.

- Turbosmart Black Comp-Gate 40mm External Wastegate.

Amazing! 3 years ago

This is an excellent product, as with anything designed and manufactured with Grimmspeed, Justin and his team do an absolute wonderful job in putting out quality products to uphold their name and outstanding track record in my eyes. I do highly recommend mocking the waste gate up as close to where you need it before installing in the car, as the Turbosmart clamps are a pain to install and tighten once you have the up pipe in the car.

QUESTIONS & ANSWERS

  • Q: Grimmspeed Uppipe EWG  thatbluesubi 7 months ago

    Got a stock 2014 sti planning on going: Invidia Q300 Catback Cobb Downpipe Catted GrimmSpeed and Turbo Smart 38/40mm EWG 2 Bolt uppipe Grimmspeed Cold air intake - Would this plus a protune be a good healthy set up to run?
    • 1 of 1 people found the following answer helpful

      A:  That would be a solid stock turbo setup. You'll want to upgrade the fuel pump, EBCS, and injectors though, as the stock injectors/pump can't really fuel enough to support that setup. The TMIC might be worth upgrading as well.

      A:  According to Grimmspeed, this will not work with the JDM STI, it would be in the way of the steering rack.

  • Q: 08 WRX  mkuchmy303143 years ago

    Looking to add this to my 08 WRX. How do I know if the spring rate of 14psi will be correct. I don't have a ebcs, do I need to get one?
    • 0 of 0 people found the following answer helpful

      A:  The spring needed will depend on your target boost level. I recommend consulting your tuner to find the correct spring pressure for your build.
