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 used by Grimmspeed is not located in the bend, which adds to the life expectancy of the flex section. The outlet size is a perfect match to the most common stock location turbos allowing for a smooth transition into the turbo.

Flow Bench Results vs. OEM

  • OEM Catless - 244.6 CFM
  • OEM Catted - 164.7 CFM
  • GrimmSpeed - 292.6 CFM

Features:

  • 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. Grimmspeeds flex joint is not located on a bend so there is very minimal flow loss(if any) through the flex
  • 14 Gauge Piping Thickness - almost all pipes on the market use 16-18(~1.5mm) thick piping wall, but not Grimmspeed. Grimmspeed uses a 2mm thick piping wall(33% thicker than all of the competition!)
  • Pipe to Flange Connection - Much smoother connection. Piping is ported flush with flange so there is no step into the pipe
  • 1.92" Inlet = Perfect match to gasket allowing a little room for gasket movement(anything bigger, ie 2", will almost be guaranteed to put the gasket in the flow which is horrible for flow)
  • 1.75" Outlet = Narrowing down from 1.92 to 1.75 acts as a funnel. Also very close match to most common turbos so you have much less step going into the turbo(unlike a straight through 2" which creates a huge step going into most common turbos vf's, tdo4s, etc)
  • Massive 304SS flanges
  • Minimal internal steps for maximum flow
  • Complete 304SS Construction (pipe, flex section, flanges)
  • Reduce turbo lag
