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.
Note that the up-pipe, as well as the wastegate dump tube, will come in a black ceramic coating to help reduce underhood engine temperatures.
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.

PEOPLE WHO VIEWED THIS ITEM ALSO VIEWED
REVIEWS & CUSTOMER MEDIA
Echoing most peoples sentiments about the pain-in-the-ass nature of uninstalling the stock up-pipe and installing the new one. Space is tight (*really tight*) but it eventually gets in. One thing not mentioned about this specific set-up, the added 3rd bolt on the flange makes this install particularly difficult (as opposed to the stock 2-bolt flange). Ultimately had to jack the engine up to get that additional 1"-1.5" clearance needed. But you get everything you pay for and it looks, sounds, and performs incredible once all bolted in and running.
This is the only prebuilt up-pipe with a EWG option for a tomei or GTspec header. If you need a EWG for your Tomei header , get this. Not only is it great quality , the ceramic coating is flawless. Over-all , the best up-pipe you could buy.

A: As Mike said, this particular uppipe is NOT compatible with the stock headers because it uses a 3 bolt lower flange and the stock headers use a 2 bolt flange.
