This is our new "symmetrical" log header designed specifically for the Wagler / Brodix head. They are 11 gauge 2 1/4" stainless steel (ss) with mild steel (ms) flanges. They flow better than the CastFlow and will make more HP.
They can also be ceramic coated to improve performance and reduce under hood temps. Customers have reported picking up 2 1/2 tenths by just bolting these on!!
2007.5 - 2010 trucks require a coolant line relocation fitting.
The optional coating will hold up to 1600 degrees prolonged. Pick your color from Black or Titanium.
You can also order these with or without a riser for the EGR.
They are custom made to order so expect 1-2 weeks build time.
