Diesel exhaust systems

In the past, diesel exhaust systems restricted exhaust flow because of the small diameter of pipe used. Sharp bends between the turbo and the rear end of the truck created back pressure throughout the system. Horsepower and gas mileage suffered. Fortunately, designs are improving

Modern diesel exhaust systems are noticeably larger than their predecessors. Exhaust flow is aided by a more direct route from front to back. This frees up additional cubic inches of breathing room needed to allow the high volume of airflow diesel engines create. These improvements in design are vital for optimum performance.

The materials and methods used to build diesel exhaust systems are also improving. Non-corrosive aluminized and stainless steel piping is becoming standard. A process called mandrel bending is used, leaving smooth surfaces throughout. Mandrel bending eliminates flat spots and wrinkles which inhibit air flow. As diesel exhaust systems continue to improve, so does the performance and efficiency of diesel engines.
