Why You Need It

The Banks Monster Exhaust is ONLY true 5" DPF-back exhaust system for 2024-2026 Chevy/GMC 2500/3500 Duramax 6.6L trucks. Increasing diameter from the stock 4" to 5" from the DPF to the tailpipe results in a measurable decrease in exhaust backpressure. This reduction in backpressure liberates power during the exhaust stroke, sharpens turbo response, and increases fuel economy.

Why It's Better

  • Improves power and fuel economy
  • The only true 5" DPF-back exhaust system
  • Side exit prevents melting your trailer during regen
  • Looks better than stock
  • Stainless steel construction

Innovative Electronics

In 2024, GM added additional emission-related checks for the exhaust system, measuring the Diesel Particulate Filter's pressure differential. When exhaust back pressure is reduced after the DPF, such as with a 5" exhaust, the engine control module thinks the DPF is over-full with soot and reduces engine power to protect itself, when in reality, the DPF may be empty and free-flowing.

To overcome this obstacle, we engineered the Banks Exhaust Pressure Control Module (U.S. Patent 12618353), which installs in-line with the DPF delta pressure sensor. The module recalibrates the DPF pressure sensor signal to the ECM, providing corrected data while permitting significantly improved exhaust flow.

Drop The Pressure

Banks negative back-pressure tip virtually eliminates back-pressure after the DPF. With a side-draft rocket nozzle-like tip, exhaust gases are literally sucked out of the end of the exhaust.

With pressure sensors installed, this negative exhaust pressure resulted in an impressive 9% reduction all the way back to the turbine inlet. No other exhaust for 2024+ Duramax trucks can provide this level of pressure reduction.

Change Your Look

Duramax owners can choose from two huge 6.5 x 7.5-inch ob-round slash-cut exhaust tips: chrome-plated polished stainless steel or high-temp Cerakote matte black. And, unlike other brands, Banks' Cerakote black or Chrome tip will not turn brown with heat.

Don't Be Decieved

With the stock exhaust nozzle measuring 2.85-inch compared to the Monster Exhausts massive 5-inch outlet, the Banks system offers a 192% greater flow area than stock.
Comparison of the Banks Monster Exhaust to the stock 2.85

The Monster Exhaust boasts 85% less backpressure than stock, leading to more power and increased fuel economy.

Drop That Heat

The Monster Exhaust also provides a 15% reduction in exhaust temperature two feet behind the tip during regen! The Diesel Particulate Filter (DPF) on the Duramax L5P is cleaned through regeneration in which scorching exhaust gas temperatures can last up to 20 minutes while driving.

Unlike the stock Duramax exhaust, which directs a prolonged jet-like blast of super-heated exhaust gas directly at anything being towed, the Monster Exhaust is aimed out to the side of the truck. This allows ambient air to diffuse the heated gas, eliminating the risk of melting a trailer, which has been reported by many Duramax owners.

Reviews

Banks Products Work!

"Like any other Banks product the fit and finish is just right. Install took no time with a lift but also wouldn’t be bad on the ground. Happy to get the exhaust off the front of my fifth wheel and it looks so much better too. Looking forward to seeing if it provides better MPGs."

— Jonathan (5/5)

Exhaust installation easy

"The instructions for installation are spot on. Taking my time it took hour and half. Just be sure to use a penetrating oil the day before. If you don’t have a lift then take a floor jack and put it on the passenger side front shackle. After you cut the exhaust jack it up and it makes removal a breeze. John B"

Exactly what I wanted!!

"2024 Duramax AT4x FOLLOW the instructions. Banks did a great job with advising of potential issues that may occur. I had to purchase a new exhaust pressure differential sensor for my truck due to the fittings being seized. That caused me to wait to install this exhaust for a short time, but worth it to keep me going down the road. The exhaust is everything I expected it to be. Installed on a garage floor in 2 hours. I’m not looking for increased sound, only functionality. I pull camper on a routine basis and wanted to reduce any future concerns with regen and exhaust heat. The exhaust turned out perfect for my truck. I’ve installed Banks products on my truck for the last two years. I’ve installed everything but boost tubes, a Derringer and oil pans. The product is spot on and worth the expense. I will be a long time Banks customer."

— Kajil S. (5/5)

Banks Never Disappoints

"I waited two years to upgrade my exhaust and now it’s installed! The wait was worth it. Looks so much better and with the added performance, it is always a PLUS."

— Grunt H. (5/5)

Banks Products Always Deliver!

"Very well made and fit perfectly. The stainless steel will be a nice touch for these newer systems. A very slight rumble in the tone is noticeable with the bigger size of the exhaust pipe. As always it looks great!"

— Joe B. (5/5)

2024 Sierra

"Installation could not have been easier. Soaked the sensors with pb blaster overnight and sprayed the hangers with silicone so the stock system came out effortlessly. Looks night and day better than the stock trumpet. Fitment was perfect. Started the truck to find no check engine light. Couldn’t ask for anything more and would expect nothing less from a Banks product. Pure perfection!"

— Mike C. (5/5)

Like the product

"I like the product . They need to inform customers on how far out shipping is . I put the exhaust on a 24 gmc long bed dually ,the web site should say that it dose or doesn't fit a daully at the top not 3/4 down the page I found out just before I am writing this . I made it fit and not touch but the tip is more angled down then I would like ."

— Chad (4/5)

Exhaust

"I have a 2024 2500 Ultimate, everything Banks makes i have on ny truck, except pedal monster and derrinfer. Just installed the exhaust i'm sure it will be great like the orher installs. Only complaint is i had to replace the part they say you may have to replace. You can just buy the tube you have to buy the whole assembly 171. 00 on top of the exhaust makes me on the fence if its worth it. With 63,500 on odometer the flaired pipe welded to the nut. Banks should make the tube and add it to the deal might cost you 15. 00. If i knew before hand or thought, i would have seen if i could have gotten the nut of before purchase."

— David R. (4/5)

Install was a breeze.

"As with all the other Banks products this kit went on with ease. I love the new look over the stock exhaust. This was the final element I needed to complete my upgrades from Banks. Intake, power elbow, boost tubes, and Derringer with I-Dash. Love them all."

— Ed R. (5/5)

Q&A

Will this exhaust system change the sound of the truck?
There will be a more pronounced tone, but it wont be an overbearing drone.
Will banks be making a dually version soon?
Hey thanks for messaging us, unfortunately we don't have a DRW kit planned at this time.
When will you have a kit for DRW?
Hey thanks for messaging us, unfortunately we don't have a DRW kit planned at this time.
does this fit a 2026 silverado crew cab short bed with a 6.6 gas motor?
This kit is for diesel trucks only. We don't offer any modern kits for gas at this time.
Is this the exhaust we should buy if we have a 2023.5 with the dual sensors on the intake?
This exhaust kit isn't compatible with 2023.5 trucks, unfortunately they have a unique emissions system that we don't plan to develop a product for at this time.
