HY35 Downpipe


An exact fit for cast Turbonetics T3 or cast Rev9 T3 manifolds. Has a quick release V-band for easy removal and a factory and/or AEM heat sink O2 bung for quick sensor response. This is set up the same as the quick release downpipe that we offer in all of our manifold/hot parts kits. It ends with a flex section/bellow right by the transfer case area (that slips over a 3″ exhaust) to be spliced/welded to your current set up or a great starting point to build off from with all the hard parts done for you.

Includes upper and lower sections and v-band clamp.


*Other manifold and turbo options can be easily built to order as long as the manifold is sent to us for mock up, please see our “Custom V-band Downpipe” listing

An exact fit with great clearance. Quick release V-band for easy removal and an AEM heat sink O2 bung for quick sensor response. Optional flex section for easy attachment to your current exhaust.

  • An exact fit with great clearance between a 1g style (pictured) oil filter and alternator.
  • 2.75″ to 3″ mandrel bends, transitioning from the exact size of the turbine housing outlet to 3″.
  • Quick release V-band, placed just before the oil pan for easy removal and serviceability.
  • AEM heat sink O2 bung for quick sensor response while keeping the wideband happy.
  • An optional flex section makes it easier to attach to your existing exhaust.
  • 100% 304 stainless steel, 100% backpurged.

There is a known slight variation from Turbonetics manifold to manifold. A second Turbonetics manifold has been tested in house for fit and worked out perfectly, with the variance being taken up by a slight orientation change at the V-band connection. There was still ample room for the oil filter to be removed (more, actually) but obviously we cannot test fit every manifold, and some manifolds are bound to be off more than others. The worst case scenario is the downpipe would have to be removed in order to remove the oil filter.

Please specify 1g/2g/GVR4/Colt/Early Evo, etc.
