Product Description
The BD DIESEL 1045948 Exhaust Pulse Manifold is the go-to durability and performance upgrade for 1988–1998 Dodge 5.9L Cummins 12-Valve trucks. This heavy-duty, multi-piece pulse manifold is engineered to solve the most common factory failure — cracked exhaust manifolds — while improving exhaust flow, reducing backpressure, and promoting faster turbo response on both stock and upgraded turbo setups.
Constructed from high-silicon ductile iron, this manifold is built to handle extreme heat cycles, vibration, towing loads, and performance driving. The multi-piece design and precision expansion joints allow the manifold to expand and contract without stressing the casting, dramatically reducing the chance of cracking or exhaust leaks. This is a direct-fit manifold designed for long service life and strong sealing under boost.

Cross-Reference & Compatible BD Diesel Products (BD DIESEL ONLY)
To complete your exhaust manifold install, we recommend pairing this manifold with additional BD Diesel installation and support components available on cppdiesel.com (verified working links only).
Will this manifold help prevent cracking compared to stock?
Yes. The multi-piece design and expansion joints allow proper thermal expansion and contraction, reducing stress that commonly causes factory manifolds to crack.
Is this a direct-fit replacement?
Yes. This manifold is designed as a direct-fit replacement for the factory 12-valve Cummins manifold using stock mounting locations and common turbo flange configurations.
Is this good for towing and daily driving?
Absolutely. This manifold is built for high heat cycles and load conditions and is an excellent reliability upgrade for towing, work trucks, and daily drivers.
