EGR stands for exhaust gas recirculation. An EGR delete kit is an aftermarket performance part that removes the EGR valve and prevents exhaust from being redirected back to the engine. Ultimately, this allows your vehicle to function as if it never had an EGR valve. There are a number of key differences you'll notice after having an EGR delete kit installed.

DPF stands for diesel particulate filter. A DPF delete pipe is a straight section of pipe that replaces the restrictive DPF. 

The Particulate Filter also known as the DPF, is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine. Wall-flow diesel particulate filters usually remove 85% or more of the soot, and can at times (heavily loaded conditions) attain soot removal efficiencies of close to 100%. A diesel-powered vehicle equipped with a functioning filter will emit no visible smoke from its exhaust pipe.

CCV resoute kits prevent oil droplets from re-entering the intake system, reducing oil deposits in the engine. Benefits: Vents crankcase blow by— decreasing oil deposits in the engine. No boot soak, intake gumming, etc.

Technically no. The biggest reason people choose a 5" system over a 4" is for sound. While both kits will lower EGTs and gain fuel mileage, the 5" system will cause you to loose a little bottom-end torque. However, one of the trucks that will benefit from a 5" kit is the new 04.5+ Dodges. Because these trucks not only already come with a 4" system but also produce so much torque at the lower end they will usually see the best results from a 5" kit.

Most build dates can be found on the information label on the inside of the driver door jam. This label will tell you anything from the VIN number to the recommended tire pressure.

In some cases, yes an enclosed system will be better. If you are mostly driving in very dusty, wet, or muddy areas an enclosed system, similar to your stock setup, is much more beneficial to you. Keeping the filter element away from debris will not only extend your filter life but also increase your overall performance and economy.

No. All of the aftermarket systems we carry are designed to be direct bolt-on with common hand tools in your driveway. In some cases, the stock system will have to be cut to get it out from under the truck but that's it.

If you have a 5th wheel or hide-away hitch on your truck that extends below the bed and inside the frame rails, this will cause an interference with the driver-side tailpipe installation. The driver-side pipe crosses over from the passenger side very close to the bottom of the bed floor. This will still clear the spare tire though.

The average install time on a single turbo back exhaust is about 1-2 hrs. A cat-back single system usually is about 0.5-1 hr. A dual exhaust usually takes a bit longer, typically around 2-3 hours. All of which can be done with common hand tools.

The typical max safety EGT setting for most aftermarket chips and tuners is 1350. That means once your exhaust gas temperatures reach this level if you have a unit that has safety features built into it, it will set off an alarm of some sort to let you know to back out of it. Most units in fact with these features will do it automatically. It's not recommended to go over that temp because, over a period of time, it can cause internal engine damage.

Actually, there is no “best programmer” for any truck. Choosing the right programmer is based on what you are using the truck for and what your main objective is with it. Now there are some units that are better than others based on what you are looking for, but the first step is deciding what you want out of your truck.

The OBD port is a 16-pin plug found at the bottom of the dashboard on all 1994 and up vehicles that allows you to read, program, and alter the vehicle's computer.
