BD Diesel PULSE EXHAUST MANIFOLD STOCK/T3 (1045947) for 1998.5-2002 Cummins 5.9L

The Exhaust Pulse Manifold for the Dodge 1998.5–2002 5.9L 24-valve Cummins engine is an aftermarket or performance upgrade designed to improve exhaust flow and turbocharger efficiency. Unlike the stock manifold, which may suffer from cracking or restrictive flow over time, a high-quality pulse manifold is typically constructed from durable cast iron or stainless steel and engineered to optimize exhaust gas velocity. By utilizing pulse tuning—where exhaust pulses from individual cylinders are timed to enhance scavenging and reduce backpressure—this manifold helps improve turbo spool-up, increase horsepower and torque, and reduce exhaust gas temperatures (EGTs). It’s a popular upgrade among diesel performance enthusiasts looking to extend engine life and boost overall performance in their late 2nd-generation Dodge Ram trucks.
