Description

This product is not emissions compliant. Off-road use only.

The Pusher SuperMax Y-Bride and Charge Pipe eliminate the anemic post intercooler charge plumbing and two piece y-bridge.

This system combines the SuperMax Y-bridge with a full 3” charge tube, maximizing air delivery from the intercooler outlet all the way to the intake plenums. Both components in this system are constructed of mandrel bent 3” tubing and CNC-machined and laser-cut flanges. The entire assembly is fully TIG-welded using precise settings that produce optimal weld penetration without impacting airflow.

The Pusher SuperMax Y-Bridge is the first true "Y" bridge introduced to the performance diesel truck market and continues to set the standard for air delivery to factory Duramax intake plenums. Its seamless one-piece design ensures optimal airflow into each cylinder head. When paired with the Pusher Passenger-side Charge Pipe, the 3" mandrel-bent tubing delivers an impressive 202% increase in airflow while following a 17% shorter flow path compared to the OEM components it replaces.

  • Fully TIG welded with precise settings to produce beautiful welds and optimal penetration without impacting air flow.
  • CNC machined flanges for flawless mounting to your Duramax engine.
  • These parts are compatible with the Pusher Max Compound Turbo System for the LLY trucks.
  • Additional options include various powder coat colors and extra ports

Thanks for making a great product!

I have an 2005 LLY with Banks 6 gun, 4 inch Banks exhaust. Prior to the Pusher Y intake install, I was getting a consistent 20.5 to 21 mpg on the highway with cruise set at 70mph. After installing the Pusher Y branch intake, my trip to the Upper Peninsula provided 23.5 mpg! I have been getting 19.5 to 20.5 mpg for in-town driving, which is far better than the prior 17 mpg I was getting in town. There is also a clear increase in acceleration and EGR temps and cooldown times.

Great product

Install was extremely tight but everything fit as it should without rubbing. Customer service is great as well, very helpful.
