Bolt-on adapters for wastegated Holset exhaust housings.  These are designed to connect these popular turbo swaps to your factory or aftermarket downpipe in a matter of minutes.

The ORIGINAL HX swap pipes for 6.5L GMT400 trucks. Things WE have that "they" don't:

  • CNC cut tapered flange for downpipe connection will properly seal just like a factory turbo
  • Custom laser cut hole spacing accommodates small variations in backing plate bolt patterns without you having to grind or elongate holes for proper fitment
  • Includes ARP stainless steel flange bolts (anti seize is recommended)

This is for the "Do it Yourself " DIY customer who needs the adapter as part of their turbo swap project.

Please choose the correct type based on the turbo you are using. PLEASE DOUBLE CHECK BEFORE ORDERING.
