Diamond Eye KIT 4in TB HX40 DWNP W/ V-Band SGL AL: 2-WHEEL DRIVE ONLY 89-93 DODGE CUMMINS 5.9L

This 4-inch turbo back exhaust kit from Diamond Eye Performance is made for 1989-1993 Dodge trucks with the 5.9L Cummins diesel engine, specifically for 2-wheel drive models. It replaces your factory exhaust system from the turbocharger all the way back, featuring a single muffler with a V-band connection for a solid seal. Upgrading your exhaust is a common step to help your engine breathe easier, especially with a performance turbocharger.

The kit is constructed from aluminized steel, which offers good resistance to corrosion for a long service life. By increasing the exhaust pipe diameter to 4 inches and using a less restrictive muffler, this system helps reduce backpressure. This can lead to improved exhaust gas scavenging from the cylinders, potentially allowing your engine to run a bit cooler and more efficiently. The V-band clamp at the turbo connection ensures a tight, leak-free seal, which is important for maintaining exhaust velocity and preventing leaks that can rob performance.

This kit is designed as a direct replacement for the stock system, meaning it should bolt up without major modifications. It's important to note that this system is not CARB approved and cannot be shipped to California. If you're looking to improve the exhaust flow on your 2WD 1st Gen Cummins, this Diamond Eye kit is a well-built option.
