Diamond Eye Performance: Exhaust Systems by Truck Guys, for Truck Guys

  • thumbnail

Diamond Eye Performance is all about trucks and truck exhaust products. The company made its name building exhaust systems for diesel trucks, but it also makes turbo downpipes, universal-fit mufflers, exhaust tips, and more. All of Diamond Eye’s R&D and manufacturing is done in-house, guaranteeing performance, quality, and fit are all second to none.

Diesel Exhaust Systems
Diamond Eye’s diesel cat-back and turbo-back exhaust systems use CNC mandrel-bent tubing to create a free-flowing exhaust path. That helps free up more horsepower, improve fuel mileage, and lower exhaust gas temperatures (EGTs). That last benefit is important if you’ve updated your truck with bigger turbos or turned up the wick with increased fuel delivery.

Diesel Turbo Downpipes
Diamond Eye Performance turbo downpipes are available in aluminized steel and T409 stainless steel with mandrel bends for greater flow. Some applications come wrapped with thermal header tape to help reduce EGTs. Downpipes are available for GM, Ford, and Dodge/Ram trucks.

Summit Racing offers Diamond Eye Performance mufflers in aluminized and 409 stainless steel with perforated/fiberglass packed or straight-through louvered cores. Summit Racing also has Diamond Eye muffler delete pipes for you race-only guys.

Summit Racing also offers the following Diamond Eye Performance products:
• Off-road and race intermediate pipes
• Muffler delete pipes
• Exhaust tubing and elbows
• Tubing, clamps, adapters, and gaskets

NOTE: Some Diamond Eye Performance products are not legal for sale or use in California and other states on any pollution-controlled motor vehicle.
