Keep Your Cool
Who: Banks Power
What: ’17-and-Up Duramax L5P 2500/3500 4-Inch Monster Exhaust
Why: The DPF-back exhaust system features constant-diameter 4-inch mandrel-bent 409 stainless steel tubing and an exclusive CoolCuff exhaust gas temperature reduction system. The Monster Exhaust with CoolCuff reduces temps as much as or more than stock while cutting power-robbing backpressure. L5P owners can choose from two beefy-looking 6x5-inch obround-angled exhaust tips, chrome-plated polished stainless steel, or high-temp matte black with a rolled edge.
