50-State Legal Drop-In Turbo and Manifold Upgrade
BD Diesel's Screamer Turbo Manifold Package pairs a Screamer HE300VG variable geometry turbo with a matched pulse-divided exhaust manifold for the 2019-2024 Ram 2500/3500 6.7L Cummins. The Screamer uses a larger Ballistic Billet compressor wheel and a Low MOI QST turbine wheel to reduce backpressure and quicken spool, supporting up to 690 horsepower with supporting modifications while remaining 50-state emissions legal under CARB EO D-553-14.
Key Features
- Screamer HE300VG turbo with Ballistic Billet 64.5mm 7+7 blade compressor wheel
- Low MOI QST 70mm 12-blade turbine wheel for reduced backpressure and quicker response
- Supports up to 690 horsepower with supporting modifications
- Pulse-divided exhaust manifold in high-silicon ductile iron resists heat cracking
- Two-piece slip joint manifold design reduces cyclic thermal fatigue
- Pre-drilled EGT probe port for easy pyrometer installation
- Fully EGR-compatible, drop-in stock replacement location
- Includes BD's HE300 turbo mounting kit with all install hardware
- 50-state legal, CARB EO D-553-14

FAQ
Is this turbo and manifold package emissions legal?Yes, this package is 50-state legal under CARB Executive Order D-553-14.
How much horsepower can this package support?Up to 690 horsepower with supporting modifications.
Is a core charge required for this turbo?Yes, a refundable core charge applies and the factory turbocharger must be returned as the core.
Does this package require tuning changes for EGR compatibility?No, the manifold and turbo are fully EGR-compatible and do not require EGR system modifications.
Is this a direct bolt-in replacement?Yes, both the turbo and manifold install in the stock location with no additional fabrication.
What is the parts warranty on this package?BD Diesel backs this Screamer turbo and manifold package with a 24-month parts warranty.
Does the manifold include an EGT probe port?Yes, the manifold ships pre-drilled for an aftermarket pyrometer probe.
What prevents the manifold from cracking under heavy use?A precision two-piece slip joint allows the manifold to expand and contract with heat cycles, reducing the cyclic thermal fatigue that cracks factory manifolds.
Installation Instructions
- Allow the engine to fully cool, then disconnect the negative battery terminal.
- Remove the turbocharger, EGR cooler connections, and heat shields to access the factory exhaust manifold per the vehicle service manual.
- Remove the factory exhaust manifold and clean all cylinder head gasket surfaces to bright metal.
- Install new gaskets and the BD Diesel manifold using the supplied Grade 10.9 bolts and spacers, torquing in a center-out crisscross pattern to 43 N路m (32 ft-lb).
- Reinstall the turbocharger, torquing turbo flange nuts in a crisscross pattern to 43 N路m (32 ft-lb).
- Reconnect the EGR cooler, heat shields, and delta-P line per factory routing.
- Reconnect the battery, start the engine, and check for exhaust leaks.
- Re-torque all manifold and turbo fasteners after the first full heat cycle.
