The Bully Dog Big Rig Ceramic Coated FTP Exhaust Manifold 85101 is a high-performance, aftermarket manifold designed for heavy-duty semi-trucks. It is specifically compatible with 1999–2003 Cummins ISX Signature 600 engines that are Non-EGR (Exhaust Gas Recirculation).

Vehicle and Engine Compatibility

This manifold is engineered as a direct bolt-on replacement for the factory center section and is compatible with the following specifications:

• Engine: Cummins ISX Signature 600 (15.0L)

• Model Years: 1999, 2000, 2001, 2002, 2003

• System Type: Non-EGR applications only

• OEM Replacement: Replaces Cummins OEM part number 3880199

Key Performance Benefits

• Temperature Reduction: The ceramic coating helps reduce Exhaust Gas Temperatures (EGTs) by 80–100°F and radiates up to 300°F less heat from the manifold surface.

• Efficiency Gains: Users typically see an improvement of 0.2 to 0.3 MPG in fuel economy and a power increase of approximately 28–32 HP.

• Turbo Response: The hand-ported and polished design increases airflow by up to 18% over stock, which significantly reduces turbo lag.

• Durability: Features thicker manifold walls and flanges compared to the OEM version to prevent common issues like warping, cracking, or leaking.
