Description
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.

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 13mm 304 SS flanges. 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.

This GrimmSpeed EWG Up-Pipe Kit was designed with the Tomei Header in mind, but may also fit most other 3 bolt flanged headers.

Nicely built Product but...
Do Boy 8 months ago
The Grimmspeed 44/45mm v-band external wastegate uppipe-3-bolt is a very nicely built up pipe. But for an up pipe that had the tomei header in mind it doesn't seem to mesh very well. It bolts right up to the manifold just fine. But the inner diameter of the grimespeed up pipe is smaller than the tomei up up pipe. So more than likely causing a bottle neck in air flow. Other than that. It is made out of very strong material. The welds and craftsman ship is spot on. Just wish they would have match the diameter of this up pipe to the tomei's. I have a Picture of my whole hand wrapping around the pipe of the grimspeed. But it won't let me upload my other picture of the me grabbing the tomei up pipe where my hand would barely reach around the pipe

    Answer

    Does this come with the vband brackets or do you have to buy separate


    • A: V band flanges are welded onto the uppipe and dump tube, but V band clamps are not included because they come with most wastegates.

  • Q: Tomioka UEL Headers  thedball 2 years ago

    Answer

    It's been made abundantly clear this works with Tomei headers and their 3 bolt pattern. Tomioka headers also have a three bolt pattern, do you know if it is compatible? The bolt pattern looks the same but it may be rotated or different bolt spacing. Compatible with Tomioka UEL Headers?


    • A: Chances are it will fit but we have not been able to confirm this first hand. I'm sure the flanges are the same but how they're rotated could be different. Mike

    • A: We unfortunately cannot confirm fitment with Tomioka headers.
