Diamond Eye Exhaust Still Flowing Freely After Years Of Abuse

When it comes to building up a diesel truck, or any vehicle for that matter, the exhaust is usually one of those things that are at the top of the list. It isn’t that expensive, you get good results, and it’s easy to do. We talked with our friends over at Diamond Eye Performance about their exhaust kits and how they’re built to last. In fact, we caught up with the IT Manager of Diamond Eye, James Reeder, and talked about his pickup truck that features a Diamond Eye system that’s lasted for over a decade.

Diamond Eye offers a full line of exhaust options for most diesel-powered pickups. These systems are available in 16-gauge aluminized steel, 409 stainless steel, and 5-inch aluminized options. You can finish your exhaust off with a custom exhaust tip or add an Exhaust Guide or Aeroturbine to enhance the sound and performance of your system.

By using high-quality materials, Diamond Eye can offer exhausts that last virtually the life of the truck. Like Reeder’s truck, the exhaust has been on for years with no rusting or leaking and that is with a ton of horsepower and torque. Plenty of hot and cold cycles with pretty big power and the exhaust is still sounding as crisp as it did on day one.

Reeder’s truck is this 2002 Dodge Ram 2500 on the outside but underneath the surface, there is quite a bit of fun. With a pair of compound turbos and a set of 275-horsepower injectors, this old Ram has pep in its step. It cranked out 856-horsepower and 1,608-lb/ft of torque on their Delta D400 DynoJet chassis dyno.

When you’re making this kind of power, you have to have the supporting mods to go along with it. Reeder said he uses a 2006 Cummins cylinder head, .093″ lines, Harland Sharp roller rockers, an Industrial Injection Dragon Fire VP44 injection pump, CP Carrilo connecting rods, DLC-coated, MAHLE fly-cut aluminum pistons. Controlling the engines every move is the Edge Products Juice With An Attitude and the power is laid down with the assistance of a dual disc South Bend clutch.

Did you know by upgrading your exhaust system you will reduce EGT's and increase horsepower, and even increase fuel mileage by reducing backflow restrictions? Diamond Eye Performance Diesel Exhaust System is just the thing you need to add good looks, increase performance, and lower EGTs. This exhaust system starts at the turbo discharge. The tubing is mandrel bent which increases performance and keeps the turbo system cooler.

Conventional exhaust systems provided by auto manufacturers are a compromise between cost and volume level. Back pressure in the pipe tends to reduce the power of the engine. Ever since the 1950s, hot rodders have developed exhaust systems that are more efficient than the stock equipment that came with the car.

Diamond Eye’s goal is to create a free-flowing pipe to extract exhaust gases that minimize horsepower reductions. Simply put — Bigger pipes work better. Most diesel pickup’s stock exhaust systems range from 3 to 3.5-inches in diameter, which is much less efficient than Diamond Eye’s 4-inch and 5-inch diameter pipes.

Their exhaust systems come in a kit that includes the necessary clamps, hangers, and brackets that are pre-arranged for easy installation. Diamond Eye exhaust systems can be installed in a little over an hour. To find out what exhaust fits your diesel truck, be sure and check out the Diamond Eye website right here.
