Features & Product Details
The Grimmspeed Up Pipe features a 44/45mm 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.

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
