for 2017-2019 Chevy/GMC 2500/3500 6.6L Duramax, L5P all cab/bed

Quicker response, more power, lower temps
4-inch constant-diameter DPF-back system, cuts back pressure, reduces tailpipe temps as much or more than stock and way more than others. Includes Chrome tip.
US Patent #5,581,111 S1
Emissions Compliant: No E.O. required
Fits all Cab and Bed lengths including Dually Models.
Does NOT fit with suspension airbags.

Designed, 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 as cool as stock, and cooler than the competition! Flowtastic! Flows up to 80 percent better than stock! Cooling as much or more than stock without killing flow is a major challenge. But Monster Exhaust wins on both counts. 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 design all along the flow path. Extensive temperature testing. Banks doesn’t just measure temperatures before and after the DPF and 6 inch from the tip. 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! Engineered design.

The diesel particulate filter (DPF) reduces smoke by turning it to ash through regeneration. This can heat exhaust gas temps to 1,100 degrees at the DPF outlet! Banks Monster Exhaust reduces these dangerous temps as much as or more than stock while also cutting backpressure. And with our eye-catching polished-stainless tailpipe tip(s), we look good doing it!
