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

Looks good

"Looks good. No sound difference of course because it’s after the muffler and dpf but it looks neat. It will help direct the heat away from my trailer when I tow. It does vibrate against my spare tire heat shield unfortunately."

— Derek R. (5/5)

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)

Looks really nice

"The installation was straight forward on the Banks side. The issue was getting the sensors out of the old pipe. As far as increased performance. I don't see any significant increases. I do think from watching the IDash Pro that the turbo spools up quicker. I can hear the turbo better but I'm not sure that is from the exhaust or just the fact that it now exits out the side of the truck now. I have seen no increase in fuel milage. One factor I did notice an increase on is that the miles between regens has gone up since putting on the exhaust. It does look a lot better than the stock exhaust and I do like the side exit a lot better. For context I have already installed on my 2024 GMC Sierra 2500HD AT4 Max Trailering, the Banks Ram Air, Turbo Elbow, MAP Relocation kit, Intercooler Pipes, Oil pan, Transmission Pan, Differential cover, Derringer, Pedal Monster, and Idash data pro and Idash pro dual pod. I've also added the Insane Diesel Extreme oil bypass filter, Scovel Motorsports PISK Kit/Steering Stabalizer, 2" Bora Wheel spacers, 35x12.5x20 Mickey Thompson baja boss a/t, Rough Country 3" Lift Kit, VSE Conversion Kit, WCFab upper radiator hose and thermostat housing, Fass Fuel Filter conversion, and Fass EGR Filter."

— Justin O. (4/5)

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)

Easy install as usual for

"Easy install as usual for Banks products, lots of room under my 25 GMC HD, was able to install without the use of jack or stands. Quality product."

— Casey S. (5/5)

Q&A

What is the ETA for dually version
We don't plan to release this kit for DRW at this time.
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.
