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

Great fitment and quality.

"Nice fitment and quality as expected from Banks. Added this with the intake and the turbo inlet and combined the truck is more spry and a little bump in fuel economy, especially unladen. The big win is not melting the race trailer and it looks good, looks appropriate. Black truck, black badges, black tip. Not over the top huge, but looks like the right size. When installing it just get the pressure delta and temp sensors, you'll never get them out of the exhaust in one piece, especially from the pipe. Did have to drill one from the DPF, but no big deal. Otherwise, fitment it top notch and there's no doubt it will last more than a decade."

— Daniel B. (5/5)

Worth it…

"If you’re on the fence in wanting to buy this, don’t be. It’s worth it. Fairly straightforward installation and looks and performs way better than stock. No more hot exhaust gases being directed at my boat, which is important during any regens."

— Timothy S. (5/5)

Outstanding upgrade!

"Great upgrade and really noticeable improvement. If you’re worried about sound it doesn’t change over stock sound! Also, outstanding shipping and packaging. Well done Gayle Banks and TEAM!"

— John J. (5/5)

Monster Exhaust

"Super easy to install. Looks great. Seems to have a little more turbo response. Very Happy with this purchase"

— Dale m. (5/5)

I love this Banks Monster Exhaust

"I purchased this exhaust as part of an overall strategy to improve performance and longevity of my truck. I don't really notice much of a sound difference but I absolutely noticed an improvement in MPG over sustained highway travel following the same route and driving conditions before installation. Plus, it looks awesome!"

— Nathan Y. (5/5)

Not as good as everyone keeps saying

"I’ve been fighting codes since I put all the banks stuff in including the exhaust. I’ve got pretty much everything they make for the 25 l5p I have another L5P with a mixture of AFE ppe and edge it’s a lot less money extremely similar in performance and I’ve never had a code my advice you don’t always get what you paid for"

— Christopher K. (5/5)

3rd vehicle to have Banks Power products

"Between the customer service and ease of ordering products from this company it has sealed us being a repeat customer. We have the exhaust, booster, inlet, cold air intake, and Derringer tuner with peddle monster. I will say, you can definitely tell the difference with the Banks products vs stock. I highly recommend these projects."

— Carri H. (5/5)

Very nice exhaust

"Looks great, easy to install. Does feel like there is less back pressure on the throttle, but gas mileage definitely dropped a little."

— Jarett F. (5/5)

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)

Aluminized Steel Exhaust

"Installation was painless and instructions included were phenomenal. Design and look are outstanding. This definitely lets my 2025 GMC 3500HD breathe. Exhaust does have a deeper throaty sound but it isn’t to much more than the stock exhaust. Why the 3 star then? Aluminized steel exhaust for $600. . This should be stainless steel for that pricing. You have to dig deep to find that in the description. This will only last 5-10yrs before needing to replace depending on the region you live in."

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.
