4" Cat back exhaust system
Dodge 5.9 Cummins from 1994-2002
This aluminized mandrel bent system is recommended as a
bare minimum in exhaust work if power modifications to the vehicle are going to
be performed. This system lets you run with a torque plate, computer module or
Torque Pro 2000 individually, but not in combination. This would require the ATS
complete 4” mandrel bent stainless system.
With the cat back exhaust system installed one can see as high as a 200 F drop
in exhaust gas temperature as a well as a 15 horsepower increase.
