GrimmSpeed and Turbosmart have joined up to give you the full package! This gives you the uppipe you have always needed and the external wastegate that dreams are made of.

GrimmSpeed 38/40mm V-Band External Wastegate Uppipe
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.
