Features & Product Details

Love your Tomei Header but wish you could go with an external wastegate? Wish no more! This GrimmSpeed Externally Gated Up-Pipe has a 3 bolt lower flange to attach beautifully to the Tomei Header.

This is the Grimmspeed External Wastegate 3-Bolt Up Pipe that features a 38/40mm external wastegate flange. This up pipe 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 GrimmSpeed EWG Up-Pipe Kit was designed with the Tomei Header in mind, but may also fit most other 3 bolt flanged headers.

GrimmSpeed 38/40mm V-Band External Wastegate Uppipe 3-Bolt ( Part Number: 007067)

I’m not a huge fan of flex piping but this is some great quality work. Welds are great. Flanges are great. I did have to lift the engine a few inches in order to get the up pipe installed but it wasn’t that hard of an install. Make sure if you get this that your header is a 3 bolt flange. I almost ordered the wrong up pipe for it but thankfully I double checked. This fit perfect with my tomei UEL header. The top bolt and nut was a PITA but doable. Great product

Easily one of the best mods I've ever done. Spool is faster and boost comes on smoother, boost control throughout the power band is greatly improved, and the sound... Mmm, the sound. Even if you're still on the stock turbo, an external wastegate is a huge upgrade and will help you maximize potential when you upgrade to a bigger turbo. Install was kind of a pain, but I also did it in my driveway with my car on jack stands. If I had used a lift the install time probably would've been cut in half. You also may need to loosen your motor mounts and jack up the motor slightly, as the EWG flange makes it a really tight fit. Overall, extremely satisfied. Don't wait, make the switch to an external wastegate. P.S. If you're going to be doing this mod, do yourself a favor and grab a set of air pump block off plates. The uppipe needs to be off in order to install the one of the passenger's side cylinder head, so might as well get it out of the way while you're in there. Definitely worth it.

Very well made Up pipe and dump tube fitment is spot on! Sounds extremely mean when boost comes on. You WILL find your self getting on boost every time someone has their windows down... weird

Do you like being heard? Do you want everyone to know where you are anytime you hit boost? Do you enjoy giving small children permanent hearing damage? If you answered yes to any of these things then congrats! This is the product for you. Now slap this on and start blowing out ear drums. Oh, and the boost control gains HP/TQ gains are noticeable and a great bonus.

QUESTIONS & ANSWERS

  • Q: Uppipe  Chris1 year ago

    Which external wastegates can you run with this uppipe? I have a tial external wastegate currently and am trying to match it up with the correct uppipe for my tomei equal length headers
    • 0 of 0 people found the following answer helpful

      A:  This wastegate will only take a 38/40 mm one. Doesn't matter which submodel you have as long as it is that size.

  • Q: Stock header  Cscarlett203 years ago

    will the 3 bolt uppipe fit with my stock uel header? 2012 wrx sedan also why would i want the 3 bolt vs the 2 bolt? I am going to purchase uppipe very soon, i have bought invida catless dp, 38mm tial wastegate now looking to but the uppipe. would like to run with stock header until i upgrade to equal length.
    • 0 of 0 people found the following answer helpful

      A:  The 3 bolt uppipe is not compatible with the stock header, and you would need a 2 bolt uppipe. A 3 bolt uppipe is made for Tomei and GT Spec headers because they use a 3 bolt flange, and there is no advantage to a 3 bolt flange.

  • Q: dump tube  imprezzme3 years ago

    is this an atmospheric dump tube or recirculating?
  • Q: gt spec header  subiejake20025 years ago

    what is the inside diameter of this uppipe?? (im running the 3 bolt gt spec header and want to make sure they match up, needs to be 2 1/4 want maximum flow turbo is garrett gt35r)
    • 0 of 0 people found the following answer helpful

      A:  The 3 bolt flange transitions from 2.25 to 1.85. This is to help channel the exhaust gasses from your large header port to the smaller inlet on the turbine housing without causing turbulence. Mike
