If you have a 2007.5-2012 6.7L Cummins, 2008-2012 6.4L or 6.7L Powerstroke, or 2007.5-2012 Duramax LMM & LML then you have a Diesel Particulate Filter “DPF” on your truck. 2011 and newer Ford Powerstroke and Chevy Duramax trucks also have a Urea Injection system. When deciding which diesel exhaust upgrades to make for your diesel, it is important to understand your choices.
So why should you upgrade your exhaust? Your stock DPF-equipped exhaust system has a catalytic converter and a particulate filter, which essentially acts as a soot trap. There are also a variety of EGT (exhaust gas temperature) and oxygen sensors. When the sensors see that the trap is full, your truck increases the EGT’s by adding fuel to incinerate the trapped soot. This process is called regeneration. During this process, the tailpipe temperatures are nearly 2.5 times higher than normal. The most common diesel performance exhaust upgrade for new model trucks is a DPF back exhaust system. DPF-back exhaust systems are designed to improve exhaust flow and cut exhaust backpressure. This is the upgrade for you if you’re interested in keeping your manufacturer warranty intact and your truck street legal in most North American locations.
Some companies like Gale Banks Engineering even make DPF Back exhausts with specifically built designs that can help lower tailpipe temperatures. And like the majority of aftermarket DPF-Back exhausts, the Banks Monster Exhaust systems are finished off with large polished stainless steel exhaust tips. A slightly enhanced, deeper exhaust note is another benefit of these exhaust systems. Most delete your stock muffler. If you’re worried that removing the muffler will make for an excessively loud diesel truck, don’t worry. The turbo, catalytic converter, and DPF filter out most of the exhaust noise. A DPF-Back system just helps your exhaust flow and makes for a better sounding truck.
