EXHAUST MANIFOLDS

This will be the LAST Manifold you'll ever purchase --- with a ZERO percent failure rate!!!

Stainless Diesel exhaust manifolds ARE MADE IN THE USA!  Pre-drilled and tapped with 2 ports for EGT & Drive. Available in T-3 , T-4  & T-6. Our Stainless Exhaust manifolds are made with shell molding to form a Super Smooth inside and out casting, that has superior flow over and above the old type 60 grit sandpaper like casting that all the Cast Iron exhaust manifolds are made from.  Back-to-back testing with our Stainless Exhaust Manifold shows a 20hp+ increase against competitors 3-piece cast iron manifold!

HERE'S A VIDEO TO SEE DATA ON US vs. THEM ( FLOW-BENCH NUMBERS @ 12:15 mark)

• Our manifold makes larger chargers more Drivable, Improves Horsepower, and extends the overall power curve. Excellent Fit & Finish. 

• Stainless Steel MANIFOLD TO CYLINDER HEAD mounting Hardware and Brass 1/8" & 1/4" NPT Plugs included. 

• Stainless Diesel 2nd gen 24v & 12v Cummins exhaust manifolds are cast with a Stainless steel "moon metal" mix made for Extreme High Heat cycling.  

• Stainless Diesel exhaust manifolds are built with 3/4"+ thick center section with room for extra porting if desired. Thick wall castings for Great Thermal control. 

• The most superior thermal energy retention for Faster spool up Accelerations. 

• Super Smooth inside runner sizing is 1.650" all the way to the center outlet for Extreme high flow. 

• Proven single piece smooth cast design has no steps that block flow in the middle like the old style 2 & 3 piece iron manifolds causing Inefficient Turbulent Air Flow Inside... Ever wonder why your stock one-piece manifold spooled better?
