Description:
This Grimmspeed up pipe features a 38/40mm external wastegate flange allowing you to convert your internally gated setup to an external, v-band wastegate with dump tube.

The entire external wastegate (EWG) up-pipe is made of 304 stainless steel (flanges, flex, tubing) and has a pipe-wall thickness of 14 gauge. This is the most "heavy-duty" pipe you will find! Many other pipes use cheap thin steel and are marketed as "super light weight."

The inlet size is 1.92" and the pipe tapers down to 1.72” which acts as a funnel as it moves into the turbo allowing for the smoothest transition and best air-flow quality.

The one-of-a-kind triple layer flex joint is not located in the bend, which adds to the life expectancy of the flex section. This outlet size is a perfect match to most common stock location turbos allowing for a smooth transition into the turbo.
  • TRIPLE LAYER Quality Flex Joint - Gives you extra durability compared to competitors single and double layer flex joints.
  • Flow through Flex - There are no big steps in the flow path of the flex joint. The flex is not located on a bend so there is very minimal flow loss(if any) through the flex.
  • Curved EWG Side Outlet - The ewg up pipes come with an angled side outlet which allows us to obtain optimal flow to the external wastegate.
  • 2.0mm Piping Thickness - almost all pipes on the market use a 1.5mm thick piping wall, not us. We use a 2mm thick piping wall (33% thicker than all of the competition!)
  • Pipe to Flange Connection - Much smoother connection. Tubes are recessed into flanges for smooth flow.
  • Massive 304SS flanges
  • 10+ whp gain
  • Minimal internal steps for maximum flow
  • Complete stainless steel construction(pipe, flex section, flanges)
  • Flex joint that is NOT located in the bend which adds life expectancy to the flex section. many other up pipes have a flex right in a sharp bend so all the exhaust/turbulence is hitting up against it.
  • Reduce turbo lag

Please Note:
The wastegate is NOT included and pictured just for installation reference.
