Description Technical Specs
This system will fit a 2016 if and only if the stock exhaust does NOT have a factory sensor bung at the top of the front tailpipe (piece that goes up and over the rear axle). 4 inch heavy-duty stainless DPF-back Monster Exhaust system with constant-diameter intermediate pipe and tailpipe. Exclusive CoolCuff design lowers tailpipe temperatures as much or more than stock while simultaneously improving flow and cutting backpressure by nearly 57%. The CoolCuff design is tested and refined by Banks engineers using Computational Fluid Dynamics software, then validated through extensive temperature testing in all areas: before and after the DPF, 6 inch out from the tip, by the spare tire, shocks, wiring, hoses, and more. First we tested our own exhaust then we tested the others. Result: Monster Exhaust measured well over a hundred dEGRees cooler than the competition, and cooler than stock, too! Flows up to 80% better than stock! Cooling as much or more than stock without killing flow is a major challenge. But Monster Exhaust wins on both counts and increases fuel efficiency in the process. Testing and Validation - Computational Fluid Dynamics (CFD) software: That's the Banks difference. Our engineers input active regeneration DPF outlet temperatures into the computer, then run flow dynamics analysis to show the cooling effect of the CoolCuff design all along the flow path. Extensive temperature testing. We also test critical systems for destructive heat exposure. Thermocouples are placed by the spare tire, shocks, wiring, hoses, and even the floor of the truck to make sure Monster Exhaust keeps everything as cool or cooler than the factory exhaust. And we don't just scrutinize our systems; we put the other guys through the same grueling tests. That's how we know they blow hot air! Banks Has the Solution. Engineered CoolCuff design. The diesel particulate filter (DPF) reduces smoke by turning it to ash through regeneration. This can heat exhaust gas temps to 1,100 deg+ at the DPF outlet! Banks Monster Exhaust with CoolCuff reduces these dangerous temps as much as or more than stock while also cutting backpressure and improving fuel economy.
