Fixing DMAX Boost Tube Flaws
Full Video Transcript
00:00 if you have an l5p Duramax or even an LML I really need to tell you about this because this is not good here’s the common problem right here you see this Gap that’s right there now what’s happening is this tube is actually separating from this tube and what’ll happen is you’ll be on the road and
00:15 it’ll pop off now this pipe is from one that I rescued from a friend of mine we had to go and Limp it back home he was Towing his boat ruin the weekend now what it was was this clamp like this was right here but it blew off and it went everywhere we had to swap it out for
00:30 this ghetto clamp right here and in the end we ended up putting one of the banks pipes on there because the banks actually makes a full kit for these both sides and it will actually increase the diameter of the pipe as well as remove all of these you can see this one was
00:44 ready to go as well and like I said if you’ve got an LML or an l5p you could probably start to see this stuff and once it starts moving like that it’s just going to blow off these clamps will hold typically because you can tighten those down pretty good but these are just crimped on so you will see
00:58 separation I definitely would suggest you go take a look and if you have any movement right there I would get a replacement pipe on the way links are in the description if you want one of the banks units however you can get the factory ones if you can because they’re
01:11 typically on back order because this is happening so often but definitely swap these out added bonus to the swap is one obviously you’re preventing yourself from having an issue and getting stuck on the side of the road but the other is going from a 2 and 1 half in diameter
01:24 pipe to a 3 and 1/2 in diameter pipe and also getting rid of this flimsy rubber hose that can collapse and tear it any any moment more flow and you won’t get the stuck on the side of the road clamps
Duramax News posted a video showing a common problem with the LML and L5P Duramax-powered trucks. The video shows the issue with the factory boost tubes, wherein the metal tube tends to separate from the hose, causing a significant boost leak, loss of power, and potentially sending the truck into reduced engine power. Better clamps are a temporary fix, but the permanent solution and upgrade is the Boost Tube Upgrade Kit by Banks.
Aside from being a fix for the popping off and collapsing boost tubes, the Banks Boost Tube Upgrade Kit boasts massive 3.5″ diameter boost tubes and are the largest on the market, flowing 26-45% more air than stock 2.5” tubes. Unlike the stock boost tubes that are made of rubber hose, the Banks boost tubes are smooth, mandrel-bent, and powder-coated steel that deliver more air to your engine while reducing boost pressure loss, resulting in quicker turbo spool and more power. Banks Boost-Tubes allow your engine, specifically your turbo, to work less hard to compress intake air, maximizing horsepower delivery and throttle response while reducing engine stress.
Better flow, faster response, and more power—Banks is the only choice in boost tubes for your Duramax.
