Features & Product Details

The  Grimmspeed 38/40mm 3 Bolt Up-pipe Wastegate Kit has been designed to allow the exhaust gasses to be diverted to the atmosphere prior to entering the turbocharger. The Turbosmart wastegate included in this kit has a larger diameter than the stock internal wastegate which allows the exhaust gas to be released faster which will improve boost control and reduce turbo lag. Additionally, this kit will help maintain maximum boost longer throughout the RPM range. Because moving the wastegate out of the turbo, you are relieving the turbocharger of any turbulence which is generated from the stock internal wastegate. Power gains can be seen from 10-40HP depending on your supporting mods.

This up-pipe has been fabricated from 304 stainless steel and features 14 gauge piping thickness which is super durable and needed when supporting the weight of a turbocharger. The inlet size is is 1.92" and the pipe will taper down to 1.72" which creates a funnel effect as it moves into the turbo which creates a smooth transition and best air-flow quality. A triple layer flex joint is implemented in the design, and it is not located on the bend of the pipe which adds more longevity. 

Users will have the option of choosing between a Turbosmart or a Tial external wastegate. And for those of you who still have the internal wastegate attached, you have the option of choosing an internal wastegate bracket which will hold the stock internal wastegate shut.

Mods: Cobb Accessport Cobb SF intake with box Cobb downpipe Cobb turbo heat shield Invidia Dual N1 catback exhaust Is there anything I need to do before I add this mod? I’m on the stock turbo

      A:  All you would really need would be a pro tune. Also, make sure you have a 3 bolt header, If you don't you would want to get the 2 bolt version.
