Fresh off the lot and only just arrived, Banks engineers wasted little time getting the new 2020 GMC Sierra Denali on the lift for its initial once-over and 3D scan. As soon as that was done, the exhaust came off and fabrication had begun!

 

Here's the tentative list of  Banks performance parts for the 2020 Duramax L5P: The 5" Zero-Backpressure Monster-Exhaust with SideKick™ tip will likely be the first part available followed by the Derringer tuner, Ram-Air cold air intake, Ram-Air diff cover, and intercooler.

 

It's no secret that the new Duramax 2500HD and 3500HD have a tow rating of up to 35,500 lbs putting the impressive 910 lb-ft of torque to good use. With that beefy tow rating comes new, heavy duty parts and better thermal management like an updated air intake system, huge 28" fan, improved radiator and intercooler as well as a new rear axle. After almost 19 years, GM engineers finally decided this was the year to update the axle housing to accommodate a giant 12" ring gear in the 3500HD. It's still a 14-bolt configuration but the pattern is a little different.

Is it legal to have all of this mods now with New EPA laws? ?

Yes the Banks parts for the '19 prior were CARB approved.

I'm sure the 2020 will be as well.

I have my Idash mounted already, I am a Banks beta tester and am anxiously awaiting my Derringer and ram air.

i was about to buy the idash and just order for the 19 from the website, if i do this and decide to add the derringer. would i just order the derringer with the switch when it comes available?

I would call Banks directly, tell them your intentions and they may let you preorder a Derringer and ship Idash now?

I did just that about a month ago, the tech who answered the phone was rude, a total dick, when I asked about 2020 he wouldn’t tell me shit just asked a simple question and the only way he would answer my question was if I pretended I had a 2019.
Not looking forward to calling them back. Wish I got his name, would like to speak directly to Mr Banks and tell him about my first and only contact with his employee

also since your a beta tester, maybe you can answer some questions?

i've noticed when the truck is working hard  there sounds like a LOT of air coming out the exhaust. to me this seems like a good sign of restriction!

thus robbed power, can you tell me if the new dpf back exhaust from banks would give me a little exhaust note rather than a whoosh sound? i assume a lot of the restriction is in the stock muffler?

also noticed a little black droplets on the front of my camper behind the exhaust, would like to know does the bank exit more to the side, verses back to the rear corner of the truck?

how many HP and TQ does it add, and is the derringer claims of 505 hp and 1001 TQ with, or without the exhaust and air box?

does the derringer lessen the turbo lag any?  does the exhaust?

i assume if you have to take it in for service you would want to remove it all. the exhaust would be a pin in the ass to swap i am sure but the derringer should be easy remove and install.

thanks for your information.

There is a restriction at the very end of the pipe just inside the intercooled tip. Other than that, it is just 4"pipe. Banks offers 4" & 5" systems, there will be no change in the tone or noise coming out.

DPF back exhaust should not void your warranty, so removal should not be necessary.

Yes the system from Banks angles more to the side.

As far as power added, Banks only lists the power gains as Derringer only, and Derringer Ramair  and exhaust combined.

Yes the Derringer will help throttle response, you won't be dissapointed.

My responses above are my experience with my '18, as the beta version of Derringer for the 2020's is not released yet, but I do have my Idash up and running on my 2020.

patiently waiting for the Derringer and Ramair. :)

i ordered my i-dash last week, i should have it monday.

the tech i spoke to was a lot nicer than the last one i talked to. he took all my info so when the new mod parts are available he can look up my acct and send me exactly what i need to do the derringer, exhaust and air filter.

From everything I have seen the architecture is the same with a few small changes that Banks touches on in one of their videos however I imagine they want to do some testing, etc prior to releasing it to the masses as a CYA for themselves.

The L5P in the 2020 HD is not the same as the 2019? I was hoping my Derringer on my current 2019 DURAMAX would swap over.

There are some minor changes to the engine such as the oil cooler and the fan. Largely the same engine with better cooling parts. The big change is the 10 spd transmission, I would assume that's why they need to do some testing and more than likely make some changes. I'm pretty excited about getting a derringer, I love being able to do some performance improvement before the warranty is gone for once.

If you are a beta tester, please take this thought back to them. I like their exhausts and I want to be in the market for one for my 2020, mainly for the cool cuff technology in conjunction with a derringer, I think that's good thinking. But every exhaust I see listed for previous trucks says it's not compatible with trucks that have airbags installed. Considering one of their marketing statements for this is that it helps divert hot exhaust away from your trailer, you'd think they'd make it a priority to make these things work together. For my use, airbags trumps the exhaust, and that removes me as a customer..... but I sure would love to do both. Just sayin'

You're thoughts have been passed along.

You CAN use the 4" exhaust with the coof cuff.

The 5" exhaust consumes too much room, between the spare tire and air bags just not enough space left

      2021 Silverado 2.7L – N232395310 – Can someone with GM dealer access check my VIN?

      By HeronLeal · Posted

      Just want to make sure it is covered by Special Coverage N232395310 Evaporative Emission Purge Pump 2021 Silverado 1500 Custom 2.7L L3B ~100k miles I'm getting DTCs P146B and P146F. VIN 3GCPWBEK2MGxxxxxx   I spoke to a person that works at GM and he said it is not covered after checking my VIN.   Is there anyone here who currently works for a GM/Chevrolet dealership and has access to GM Global Warranty Management / Investigate Vehicle History who could explain how the VIN eligibility is determined?   thank you

      Tire psi

      By jgaudet99 · Posted

      Thanks for all that information, I might purchase one and see if it will work for me, if not they may let me return it! Yes for sure the tires are definitely within limit for my truck empty, and when I do tow I'll definitely make sure to raise the rear psi for the amount of weight that's going to be on it.

      Tire psi

      By Chuck FB · Posted

      Yes exactly, more and more these days people/companies are afraid of liability issues so its easier just to say no rather than risk putting their neck on the line.    I will say with the Autel unit or when I used it last year on my truck, it wasn't like I could choose the 2025 model year or even the 2024 model year as that option was not there to manipulate the placard pressures but had to go back to 2023 or there abouts and then it showed up as an option, odd but that was how the software was then and I can't say one way or the other now as they throw out updates every so often. I still would talk to your tire dealer though to start with and they may do it for nothing but also they may have a comment on a better unit to purchase. All I know is that one of the large tire shops in my area happens to use these Autel units for their use and set them up to use the wifi and all of that jazz for constant updating because each tire tech has one handed to them by the shop but I just plugged it into my laptop to update it and yes if one is bought it has to be registered so you can get the link to do updates and then the unit has to be updated before its even used. I am not at all techy so it took me a bit but anyway just a heads up for anything you buy, most likely it will need to be connected to a computer to access the internet to have it updated to the latest software version before you can put it to use.   If your truck is near empty, those tire pressures you listed are a very safe upper range pressures to carry the weight, both the front and rear as I know they could be run lower yet with an empty truck. And if its a trailer and not some motorcycle your going to strap onto the front of your truck on a rack, you shouldn't have a need to inflate your front tires if your at 55 front already, its the rear ones that would need more air if you have much hitch weight.

      Thank you, I'll check that Autel scanner out and see if it will work for me! Ya I can see GM's point of view if they lower the psi set value for someone and the person sell's the truck and the new owner puts the factory tires back on then their could be liability issues cause the psi warning light wasn't coming on when the tires were under inflated for towing their load and then it might be able to be traced back to GM lowering it.

      I had a similar but different response when I talked to the service manager where I bought my truck in that he said GM corporate won't allow them to lower the placard pressure setting as they would get their hand slapped but that of course they have the ability to make that change. His suggestion was simply go to a tire dealer or third party shop that is willing to reset the pressures lower. However I chose to buy a tpms tool and partly based off of this very forum as it had been proven to work on the 2024 model ( Global B system ) and while I could have paid lots for a full two way diag tool, I didn't want to spend that much and bought the recommended Autel TS 508 and it will reprogram the 2025 model and assume it should do the 2026 as well. However the tool is rather proprietary to reprogramming Autel tpms sensors so that is a function I will never use, where as a real two way scanner would have many uses but also have yearly subscriptions etc where this 508 is free updates for as long as they put updates out for the unit. In any event it worked to lower the placard pressures and I often use it to adjust my actual tire pressures although will check with a mechanical gauge as well sometimes just to make sure that tires tpms sensor isn't lying to me.    My suggestion is either buy a tool that you know will work to adjust the system or start out by getting the tire shop you bought your tires from to reset your truck and if after that you still want a unit to do it yourself, get one at that point.
