Introducing the new 4″ Monster Exhaust with CoolCuff for the 2017-2018 GM 6.6L Duramax L5P 2500HD/3500HD. The DPF-back exhaust system features constant-diameter 4″ mandrel bent 409 stainless steel tubing and the exclusive CoolCuff exhaust gas temperature reduction system.
The Diesel Particulate Filter (DPF) on the Duramax L5P is cleaned through a process called regeneration. Exhaust gas temperatures greater than 1000° are produced at the DPF outlet during regen. Unlike other aftermarket exhausts, the Monster Exhaust with CoolCuff reduces temps as much as or more than stock while cutting power-robbing backpressure. Also, real-world testing of the Monster Exhaust during regen revealed an average reduction of 350° when compared to stock at 8″ from the tip during highway cruising. The CoolCuff is the key.
Unlike competitors’ systems that offer ineffective perforations around the circumference of the tip, the CoolCuff is located inboard, drawing cool air from outside the exhaust, reducing the temperature of the hot exhaust gasses before exiting the tailpipe. When testing in regen on the dyno, competitors’ temps 8″ from the tip ranged from 770° to 802°, while the Monster Exhaust measured a cool 485°. That’vs 317° less than the competitors and 32° below stock!
Since the L5P’s launch in 2016, owners have shared concerns that the high exhaust temps have resulted in deformed or blackened trailers caused by prolonged blasts of superheated exhaust. Banks Monster Exhaust with CoolCuff was designed to solve this.
L5P owners can choose from two beefy-looking 6″ x 5″ ob-round angled exhaust tips; chrome-plated polished stainless steel or high temp matte black with rolled edge. And, unlike other brands, Banks’ chrome-plated stainless tip will not turn brown with heat.
The Banks 4″ Monster Exhaust with CoolCuff (Part No. 48947 for chrome or 48947-B for black) fits all regular cab short bed, double cab short bed, double cab long bed, crew cab short bed and crew cab long bed models and is now available via Banks Power authorized dealers and bankspower.com/L5P at a low $449.99.
