Features & Product Details

This is the Grimmspeed External Wastegate 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. 

Aside from the up pipe, a dump tube is provided, along with all the hardware and gaskets to make this up pipe ready for the installation. 

Note that this up pipe is not suitable for RHD cars.

This product does exactly what you buy it to do. It's not a terrible install just a lot of wiggling around to get it up in there (absolutely no reason to pull your mount and jack your engine, as you will find people saying all over the internet) The vband is a nice edition in the confined space you have to put your ewg. I have no experience with any other up pipe however after doing the job I would recommend looking into the Perrin rortated pipe. The grimmspeed leaves you SO little room for your ewg and dump tube. It can be a big pain in the butt to get all the fittment right depending on what downpipe you have. that said the Perrin would give you twice as much room at twice the price . To conclude; if your working on a budget this pipe is great and does the job perfectly. My complaints are entirely based around the install. Once everything is fitted up right you will never have an issue with it. Disclaimer; if you have the turbo xs 4" to 3" dp this is probably not the up pipe for you. It's not impossible but damn near close. With that dp it makes it so u can only turn the bottom turbo to dp nut a 16th of a turn at a time.

UPPIPE EWG 4 years ago
awdturbowrx
I bought this part knowing Grimmspeed has very good quality and craftsmanship. I was impressed with the parts I received and thought everything was solid, clean and packaged great. Fitment of the Uppipe was not as good as I would of liked to of seen but still managed to line up good in the end. The dump tube is just god awful if you have any sort of cat. Good thing I had to take the Downpipe off because i noticed it was clogged so i cut it out and managed to fit the dump tube, but I think different selection tubes would make people happier. So 3 stars mostly because of the dump tube, id give the up pipe itself 4/5. Good solid parts.

GrimmSpeed EWG uppipe 4 years ago
charlesewing
I purchased one of these up pipes earlier this year and found the quality to be WAY better than the previous ones iv had (avoid invidia,and perrin) That being said the part did crack where the pipe braches out to connect the waste gate. Iv already spoken to the guys at grim speed and within a 5 minute phone call was able to get a replacement on its way.Reasons for the crack are unknown at this moment but hopefully the guys will be able to sort it out once i ship the old one back. It could have hit something or it could be my set up. regardless the product is still a quality piece and I would recommend it before any others. Lastly Id like to point out that Grimm Speeds customer service was on point and better than most if not all the other companies iv dealt with

QUESTIONS & ANSWERS

  • Q: Vehicle fitment  Mr Phil3 years ago

    Your vehicle description at the top of the page says it will not fit my 2002 WRX. But if you go on GrimmSpeed page directly and search for parts for a 2002 WRX this exact same part comes up. Is there anything different from this one compared to the one that's on their website?
    • 0 of 0 people found the following answer helpful

      A:  Since this removes a factory emissions device we are no longer able to confirm fitment for the earlier model WRXs which include a catalytic converter in the uppipe.

  • Q: GrimSpeed uppipe with wastegate  2013wrx6033 years ago

    I am currently at stage 2. Codd accessport, sf intake, invidia downpipe, and magnaflow catback. I do not have a external wastegate. My question is should I get the Tail MV-S wastegate 38mm or get the GrimmSpeed 38/40 V-Band External Wastegate Uppipe? I am planning on getting the process west vertical top mount intercooler along with a few other mods. Thanks.
    • 0 of 0 people found the following answer helpful

      A:  This up pipe is designed to be used with the External Wastegate. So you would need both the Tial MV-S 38mm Wastegate and this up pipe to complete the install.

  • Q: Fitment  Jon3 years ago

    I'm looking into a turbo swap for my 2006 wrx. I have a 3 inch Invidia catless downpipe and want to upgrade to a vf39 turbo. To my understanding there is an wastegate that is connected to the turbo and the aftermarket uppipe (the one I'm asking about) will connect to the wastegate. So I will just have to buy this part and this also to go along with it? --> http://www.rallysportdirect.com/shop/product/tbs-ts-0505-1006-turbosmart-comp-gate40-wastegate-black
    • 0 of 0 people found the following answer helpful

      A:  The VF39 already has an internal wastegate just like your factory turbocharger. This uppipe would not be required for that kind of a setup but external wastegates can be more efficient over the internal wastegate and this is optional.

    Will the tial 38mm ewg, Part #: TIA MVSB work with this up pipe?
  • Q: bracket for 09 wrx  joe2008me284444 years ago

    Do you have to buy a bracket seperatly or does it come with one already?
    • 0 of 0 people found the following answer helpful

      A:  Which bracket are you referring to? If it is an internal wastegate bracket that must be purchased separately since it depends on the type of turbocharger you have.
