The Particulate Filter also know 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 condition) attain soot removal efficiencies of close to 100%. A diesel-powered vehicle equipped with functioning filter will emit no visible smoke from its exhaust pipe.
FLOW! That is the main reason to go with an aftermarket mandrel bent exhaust system. What is mandrel bent you ask? Mandrel bending is a process in which the exhaust tubing is bent in a way that there are no “crinkles” or indentations in the piping causing a reduction in airflow, meaning that the piping is the same diameter throughout the entire exhaust system. Typical gains are increased throttle response; lower exhaust temps, better fuel mileage and big smile on your face.
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.
The OBD port a 16pin plug found at the bottom of the dashboard on all 1994 and up vehicles that allows you to read, program and alter the vehicles computer.
The typical max safety EGT setting for most aftermarket chips and tuners are 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 time it can cause internal engine damage.
409 stainless will get surface rust however it will never rust through. The reason for that is it’s not 100% stainless. It has 11% chromium and 1% manganese.
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 set up, is much more beneficial to you. By keeping the filter element away from debris it 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 tail pipe installation. As you can see in the picture 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. If you have any questions on if a kit will fit your truck please call in advance.
Average install time on a single turbo back exhaust is about 1-2 hrs. A cat-back single system usually is about .5-1 hr. A dual exhaust usually takes a bit longer, typically around 2-3hrs. All of which can be done with common hand tools.
A core charge is an acronym for "Cash On Return". These are rebuildable parts that can usually be redeemed for a portion of their original purchase price. Most companies will reuse the case of a transmission, the core of a valve body or even an internal part of a torque converter that is either no longer available or much to expensive to buy new and can be reused on the newly manufactured part. These charges are refundable though once you send in your original part.
