Evo 8/9 Downpipe w/ V-band Disconnect

Based on several requests for a two piece configuration we have finally released a v-band version that retains a full 3" diameter throughout! This option is only available with a recirculated wastegate dump.

Please Note: It very important to select the correct block option below so we can properly build your downpipe to fit.


  • Full 3" design reduces exhaust restrictions and is the only true 3" option available!
  • Made from 304 SS for superior corrosion resistance and enhanced appearance.
  • Mandrel bent tubing throughout optimizes exhaust flow.
  • SS flex section reduces stress from engine movement increasing longevity.
  • Optimal wastegate dump location helps eliminate boost creep.
  • Integrated Wideband O2 Bung
  • Fits all Evolution 8 & 9 including those equipped with an Active Center Differential (ACD).
  • 100% Made in the USA.


  • Recirculated wastegate dump: Standard O2 housing configurations recirculate the wastegate gases just inches away from the turbine outlet resulting in turbulence and decreased performance. Our unit recirculates the wastegate gases as far away from the turbine outlet as possible to provide you with the best possible performance without the additional noise from the external dump.
  • Test Pipe / High Flow Catalyst: Further increase exhaust flow by adding either a test pipe or high flow catalyst to your purchase. Please note this is a separate component.

CNC 3D Countoured Flange

We offer this product with CNC 3D contoured flange, the standard flange has been performing flawlessly for the majority of our customers since this product's inception in 2009, but there have been a handful of customers that experienced boost creep when trying to run lower boost levels (less than 25psi) with upgraded turbochargers.
