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

This 4-inch turbo back exhaust system from Diamond Eye Performance is built specifically for the 1989-1993 Dodge trucks equipped with the 5.9L Cummins engine and 4-wheel drive. If you're looking to get more out of your Cummins, a larger diameter exhaust like this can help your turbo spool faster and reduce exhaust gas temperatures, especially when you're towing or pushing the engine hard. This kit replaces the entire exhaust system from the turbocharger back to the rear bumper, including the muffler and tailpipe.

Constructed from aluminized steel, this kit is well-built to handle the rigors of daily driving and heavy use. The 4-inch diameter tubing offers a significant increase in flow compared to the stock exhaust, which can lead to a noticeable improvement in throttle response and a deeper, more aggressive exhaust tone. The kit includes a single muffler designed for optimal flow and a V-band clamp for a secure connection at the turbo outlet. Diamond Eye Performance is known for making exhaust systems that are straightforward to install, typically bolting up to the factory mounting points.

Please note that this exhaust system is not CARB approved and cannot be shipped to California. It's designed to be a direct replacement for the factory exhaust, making installation as simple as possible. You'll likely notice a more robust sound from your Cummins once this system is installed.
