Q: What is the max EGT I can safely run my truck at?
We like to see exhaust temperatures below 1250˚F but most trucks can take temperatures up to 1350˚F for short periods of time.
Q: Is an enclosed intake system better than a open-style?
An open intake system will usually support slightly more airflow, but If you are using the truck in extremely dirty conditions, we would recommend an enclosed intake system, which would be more protected from dirt.
Q: What is a particulate filter?
A Diesel Particulate filter (also known as a DPF), is an exhaust filter designed to remove particulate matter (soot) from the exhaust of a diesel engine. As the filter becomes filled with soot and the backpressure increases, the truck enters ‘Regeneration mode’. Using fuel the DPF is superheated and burns up the soot. This greatly reduces the amount of emissions produced but can also cause a decrease in fuel economy. They are installed on trucks built after February of 2007.
Q: What exhaust system should I buy.
In most cases a 4” aluminized exhaust will work fine. It is the cheapest option and in most environments will hold up well. For those of you who live farther north where rust becomes a problem, you might want to consider purchasing a stainless kit. Although 409 Stainless will develop surface rust, it will never rust completely through. Wondering about 5” versus 4”? The main reason people choose a 5” exhaust is for better sound. There is no performance or fuel mileage benefit.
