KNOWLEDGE HUB

Everything you need to know about D&J Cummins exhaust manifolds.

Pick your mount style first: stock/HE351, T3, T4/T6, or specialty options like wastegated and 20-degree manifolds for larger turbos. Many options use high-silicon ductile iron and slip/expansion joints to handle heat cycling and help prevent cracking and leaks, and kits simplify installs by including gaskets, bolts, and spacers.

  • Stock mount and upgrade flange options Choose stock/HE351, T3, T4, T6, or specialty manifolds based on your turbo and goals.
  • Pulse manifold design Fully divided pulse manifolds are designed to improve spool and reduce back-pressure for stock and performance setups.
  • Built for heat cycling High-silicon ductile iron + slip/expansion joints help resist cracking and exhaust leaks from thermal fatigue.
  • Complete install kits available Manifold kits include the gaskets, bolts, and spacers you need for a faster, cleaner install.
  • Hardware and gasket support Gasket sets and bolt/spacer kits help keep sealing consistent after repeated heat cycles.

FAQs

Which exhaust manifold mount do I need, stock, T3, T4, or T6?
Match your turbo flange first (stock/HE351, T3, T4, or T6), then match your year range/engine (5.9 or 6.7).
What’s the difference between an exhaust manifold and an exhaust manifold kit?
A kit includes the manifold plus install items like gaskets, bolts, and spacers (varies by kit).
Do these manifolds help reduce cracking and exhaust leaks?
Many designs use high-silicon ductile iron with slip/expansion joints to reduce thermal fatigue and help prevent cracking/leaks.
Are manifolds pre-drilled for pyrometer probes?
Many options list ports pre-drilled for pyrometer probes (check the product’s FEATURES).
What is a “pulse” manifold?
A fully divided pulse manifold separates flow paths to extract exhaust pulses for quicker spool and improved response.
When should I choose a wastegated manifold?
If you’re building around an external gate setup, wastegated manifolds are designed with a dedicated gate port and divided flow.
Are any of these not for sale in California?
Several manifold products note “Not for sale on licensed California vehicles” in the product ATTENTION section.
Should I replace bolts/spacers when installing a new manifold?
Yes, fresh bolts and spacers help handle heat cycles and reduce the chance of fatigue/stretch and repeat leaks.
