1988-1998 12-valve 3-piece

Exhaust Manifold - 1988-1998 Dodge 12-valve

Great as a stock replacement, our exhaust manifolds were designed with expansion joints and heavy webbing to prevent cracking. The exhaust runner design maintains exhaust velocity to drive the turbine wheel. Runner size does not go beyond the size of the exhaust ports on the head because when the runners are larger, the velocity to drive the turbo is lost due to the expansion and temperature in the exhaust manifold reduces the turbine drive pressure needed for turbocharger response.
 
On engines with enhanced fuel flow and larger turbochargers, the principal remains the same. Velocity and temperatures are needed to drive the turbine wheel which turns the larger compressor wheel that supplies the extra volume to attain proper air-to-fuel ratios.
 
BD’s 1-Piece Stainless Exhaust Manifolds do not require the expansion joints because of the ability of the Stainless Steel to withstand higher heat without cracking.

1045995-T4

1998.5-2014 5.9L/6.7L w/T4 Mount

With BD's new T4 exhaust manifold, you can experience a larger runner size, which helps enhance flow through the manifolds with no restriction throughout the RPMs. Cast ports and runners match inlet gasket within 0.03” T4-T6 and center mount can face down or up.

This optimizes to a 20° rather than 40° which greatly helps when mounting S400, S500 and other larger turbos.

Created from HiSi Ductile iron, this heavy cast exhaust manifold has 2 drilled and tapped 1/8-NPT ports with heat expansion joints to prevent cracking.

Note: These manifolds are intended for the installation of competition turbos and some modifications to vehicle/engine components will be necessary. Common Turbos with T4 or T6 mounts include: Borg Warner S300 / S400 / S500 Holset HX50 / HX55 / HX60 / HX82 Garrett GT40 / GT42 / GT45 / GT47 / GT55.

1998-2002 24-valve 1-piece

BD Diesel Performance's Stainless Steel Exhaust Manifolds are designed to withstand temperatures that exceed 2000°F without warping or fracturing. These award-winning manifolds aren't just tough, the reflective capacity of their stainless steel design enables them to maintain the exhaust temperature and velocity which ensures maximum drive pressure reaches the turbocharger. The T3 flange assists in maintaining velocity; it can also connect to a T4 mount with the help of an adapter plate or a BD Turbine Diverter valve.

These manifolds fit Dodge 5.9L 1998-2002 24 Valve diesel trucks.

Note: this manifold can be used as a direct replacement for Cummins part number 3946036 used on pick-up engines.

Note: these manifolds turn a sweet-looking gold color after they have been heated.
