Performance Exhaust Systems for Chevy Diesel Trucks
Diesel
engines need plenty of air to produce power and proper emissions. When you are pulling up
a hill or accelerating, a high flow exhaust is critical for good engine performance.
The DuraMax engine is a high speed diesel that needs to breath. Increasing the exhaust to
a 4" mandrel bent system with a high flow muffler improves the turbo response. Quiet,
there is a DuraMax running.
On the original 6.5 engine installation, the turbo down pipe is attached and results in a
crushed pipe. On the original 6.5 exhaust, there are flow restrictions at the turbo outlet
pipe and in the muffler. The rest of the pipe is usually only a 2.75" diameter. Our
3" and 4" full mandrel bent aluminized pipe corrects the problem, giving the
engine what it needs: improved turbo response and high airflow ability.
High flow air filters are recommended to complete these performance kits.
