This 4" 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. Available with stainless or black tips to match the style of your truck.
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" out from the tip, by the spare tire, shocks, wiring, hoses, and more. First Bank's tested their own exhaust then they tested the others. Result: Monster Exhaust measured well over a hundred degrees cooler than the competition, and cooler than stock, too!
The system includes a huge 6X5" polished-stainless rolled-edge tailpipe tip, and comes with a Lifetime Warranty.
Flowtastic! - 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. Their 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 - Banks doesn't just measure temperatures before and after the DPF and 6" from the tip. They 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 Bank's doesn't just scrutinize our systems; they put the other guys through the same grueling tests. That's how Bank's knows 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‚°+ 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. And with the option of eye-catching polished-stainless tailpipe tip(s) or black tailpipe tip(s), you'll look good doing it!
IMPORTANT NOTE: This system is not compatible with Regular Cab models

Will this fit my 2015 GMC 3500 dually?
Yes it will fit Dually applications.
Will this fit a 2016 Denali HD LML. Everything I've seen only shows up to 2015?
Looks like the website just needs to be updated. This system will work on a 2016 as well. -TL
is this just a muffler delete??
Yes, this would remove the factory muffler and come from the factory DPF back. -AW
