Diamond Eye Exhaust

If you are seeking a striking look, feel and outstanding capabilities for your truck, augment your truck with exhaust systems, kits and components from Diamond Eye Performance.  Diamond Eye supplies affordable, easy to install exhaust modifiers that will make your truck stand out.  Diamond Eye components are compatible with Dodge Cummins, Ford Powerstroke, and Chevy Duramax diesel powered trucks.

Modified exhaust systems give your truck a powerful image and sound, while also improving the performance of your fuel and exhaust system.  Moving through a wider path, exhaust escape more easily, thereby increasing fuel economy and lowering EGTS.  By eliminating backpressure limiting your engine, you also enjoy enhanced horsepower and torque, as well as more responsive throttle.  Diamond Eye kits and components are made from high-quality aluminized steel and stainless steel with 1 to 6 year warranties to ensure your upgraded system performs precisely as it should.

Exhaust modifications are an ideal place to start modifying your truck, with noticeable differences in capability and performance.  Browse exhaust kits from Diamond Eyes Performance to find affordable kits for a variety of diesel trucks. 


IMPORTANT NOTE: Due to varying laws and regulations, most Diamond Eye exhaust systems & components cannot ship to California. Take a look at our product selection for alternatives from other manufacturers if you are in California. If you have any questions about other options, please give us a call or send us an e-mail, we'd be happy to help.
