From Banks Power: "To address questions about performance gains, it's completely understandable why someone would think that adding a DPF-back exhaust couldn't possibly improve performance But it can and here's why. Your turbo's compressor and turbine wheels are connected via a common shaft. The less work the compressor, which means it can create more boost while using less energy to do it. Here's a good way to visualize what's happening. Put a drinking straw in your mouth and plug your noes It's difficult to breathe through the straw, but it is possible. Now add a few lengths of straw and try to breathe. Your lungs are not strong enough to overcome the backpressure. Now imagine increasing the diameter of those drinking straws to an inch. Now you can breathe with almost no effort. Increasing the diameter of the exhaust appears to the engine as shorter length of tubing. Remember, the engine only makes power on one stroke; the power stroke. The other three strokes consume power. If you can reduce the energy consumed tne power stroke.. If you can reduce the energy consumed by the crankshaft to expel exhaust gas during the exhaust stroke, you've liberated otherwise lost horsepower."
Banks definitely understand engineering better than many throwing on random parts. Yes, the DPF does add back pressure but you can reduce back pressure elsewhere in the entire system and still make good power. Point is you don't have to be deleted just to make power with a tune
@@Tyler-vt8dr hey man I'm 15 wanting to become a mechanic and I know I can take the schooling for it at 16 but I was wandering what you did to get into it, I was thinking about auto body repair or just regular automotive technition, any input?
Figured as much. It damn well don’t matter if they make the same power with or without emissions. What matters is temp. Take a gander and the emission compliant exhaust. There’s yellow/ gold, blue/ purple tones. This is from excessive heat. The only time I’ve seen discoloration in a deleted diesel is on race trucks that are pushing a whole lot more power, more air, and obviously.. more heat. Do. No. Buy. Emissions. Compliant. Exhaust. And don’t buy emissions compliant tunes. At that point, if you’re not pulling. Buy a gas truck.
That’s why you don’t get a truck with an emissions system lol get a lbz,lb7 or LLY you can do what you want since there’s no def system i used to go by cops all the time in my dually all the time hauling hay and the thing smoked like a run away locomotive
@JWMontoya I understand that it keeps the dpf. The vast majority of exhaust kits are muffler back. If it had an aftermarket muffler or no muffler it would sound much different.
Its the l5ps computer thats the problem, not the tuner. Somehow gm made the pcm impossible to flash, and the easy way of deleting is to buy a new already unlocked computer. Idk, shits dumb
@@HK416DSF well the one in this video is a l5p if that is what you have it could be anywhere from 6-8k there expensive to do when you do it the engine it’s self will run cleaner last longer you’ll get better mileage and lower egts( exhaust gas temperature ) and the engine can breathe a lot better you’ll get better throttle response. And you’ll get more turbo noise just over all it improves the preformance and longevity of the truck.
@@HK416DSF that price is to have someone do it for you you can order all the stuff and do it your self but if you don’t have experience doing it I highly recommend you take it to someone educated and have it done.
Just run the stock 4” piping 5 inch is useless for that stock engine only thing your doing is adding more weight to your truck and saying to others hey i got money for stupid shit 🤷🏼♂️
