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.

The goal of Diamond Eye 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 CNC mandtdrel-bending machines and support equipment allow them to fabricate non-restrictive, free-flowing systems that your diesel engine will profit by. Diamond Eye affords you the choice of standard and muffler replacement kits (RP) in 3.5 in. up to bigger and better 5.0 in. systems, in either economical 16-gauge aluminized steel or longer-lasting, good looking 409 stainless steel.

Diamond Eye exhaust systems come in a kit that includes the necessary clamps, hangers and brackets that are prearranged for easy installation. Diamond Eye exhaust systems can be installed in a little over an hour.
