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.

Very well made Up pipe and dump tube fitment is spot on! Sounds extremely mean when boost comes on. You WILL find your self getting on boost every time someone has their windows down... weird

Do you like being heard? Do you want everyone to know where you are anytime you hit boost? Do you enjoy giving small children permanent hearing damage? If you answered yes to any of these things then congrats! This is the product for you. Now slap this on and start blowing out ear drums. Oh, and the boost control gains HP/TQ gains are noticeable and a great bonus.

  • AnswerQ: gt spec header  subiejake2002 2 years ago

    what is the inside diameter of this uppipe?? (im running the 3 bolt gt spec header and want to make sure they match up, needs to be 2 1/4 want maximum flow turbo is garrett gt35r)

    • A: The 3 bolt flange transitions from 2.25 to 1.85. This is to help channel the exhaust gasses from your large header port to the smaller inlet on the turbine housing without causing turbulence. Mike
