From big bore intake stacks, and manifolds, to super sized six inch bore exhaust pipes, getting diesel power doesn’t get any easier. We want to explain to you how any person with a few simple tools can go out in the garage, or in the front yard, pop open the hood to their diesel powered engine, and begin cranking up the horsepower. Letting an engine breath is a great way to free up some ponies that were restricted at the factory, but you have to make sure that they are emissions legal in your state before you make these modifications. Not being able to pass a smog test means you can’t register your vehicle in some states, but in my personal location in Florida, we don’t have any emissions laws, and people run around with exhausts taken completely off of cars all the time. The reasons manufacturers restrict the diesel engine power is because of these very emissions tests, and because the laws are so strict on new car manufacturers, the producers of these vehicles absolutely have to ensure they meet every states codes. This means putting on restrictions that your state may not require.

If you are wanting to begin freeing up some diesel power that has been cut off back at the factory, then you want to begin by looking at the way your engines intake it set up. If there is a restrictive air box surrounding the air filter, then you are probably going to be able to get a couple of ponies out from under the hood. All you will have to do is purchase an after market air filter that is open, and then remove the air box assembly and save it for a later date, in case you want to sell the truck. This one mod will help the engine breath in a lot easier.

As for breathing out the used exhaust fumes, your diesel powered engine is going to need some bigger exhaust pipes. In most states, there aren’t a lot of requirements on the size of the pipes you can use, but manufacturers still restrict it because of different states emissions laws regarding diesel powered engines. If the pipes are 2 inch or even 3 inch sized pipes, you can probably increase them to 4 inches, or even larger if you are using a fuel map programmer type of unit.
