Choosing the Right Diesel Performance Exhaust System for Your Diesel Truck (part 2 of 2)

March 26, 2012

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.

Choosing the Right Diesel Performance Exhaust System for Your Diesel Truck (part 1 of 2)

March 13, 2012

It’s widely known that upgrading your factory system to a performance diesel exhaust is a great way to increase your engine’s power and fuel economy.   Because of all the changes to stock emissions systems over the past few years, there now exists some confusion and questions among diesel owners as to which exhaust upgrade is the best option for them.   Parleys Diesel Performance wants to help you make an informed and educated choice, so let’s start by reviewing the basics.

Traditionally, light duty diesel truck factory exhaust systems were 3 inches or 3.5 inches in diameter, with crimped spots along the diesel exhaust system that hampered flow and robbed your vehicle of its true potential.   Installing a performance system to increase the diameter of your exhaust allowed your engine to expel exhaust gasses more efficiently, and mandrel bends gave your exhaust a true 4″ diameter.  Diesel trucks today come from the factory with catalytic converters, diesel particulate filters, even urea injection systems (also called SCR or selective catalytic reduction).  And 4 inch stock exhausts are commonplace.

So which exhaust should you choose for your truck?

If you have a “pre-DPF” diesel pickup (anything before the 2007.5 6.7L Cummins, 2008 6.4L Powerstroke, or 2007.5 Duramax LMM) the most common diesel exhaust upgrade is a four inch turbo back exhaust system.  The standard 4″ diameter will meet most people’s needs; however, if it’s your intention to upgrade your vehicle to a high horsepower level (think over 550HP), we recommend you invest in a 5″ diesel performance exhaust system. This will allow the larger amount of exhaust your high horsepower diesel creates to flow properly and keeping temperatures down.

In addition to figuring out the diameter of the exhaust system you want for your truck, there are also some other important choices to make.  Diesel exhaust systems come in four main materials: T-304 Stainless Steel (high-polish show finish quality), 409 Stainless Steel , Aluminized Steel (similar to your original stock exhaust), and different variations of Black Stainless or Black Aluminized Steel.   You also need to decide whether you want to have a muffler or not, and if you do choose a muffler, do you want one that is a high flow performance muffler or one that keeps your exhaust volume low.  The majority of Turbo-Back Exhausts come with high flow performance mufflers.  If you want a “straight pipe” exhaust, meaning no muffler, a popular choice is the no-muffler series from MBRP Performance Exhaust.  Their stainless steel SLM (Stainless Less Muffler) and PLM (Performance Less Muffler – this is aluminized steel)  are very competitively priced and work great.

Although less popular, catalytic converter or Cat-Back Diesel Exhausts allow you to upgrade the sound and flow of your exhaust and in some areas are necessary to keep your diesel street legal.

Chevy & GMC Duramax LML Diesel Exhaust Solution

March 8, 2012

If you are like many new Chevy Silverado HD & GMC Sierra HD owners, you’re looking for options and ways to upgrade the look and sound of your new diesel.  May we suggest for your 2011-2012 Duramax 6.6L LML exhaust the new performance diesel exhaust system from Gale Banks Engineering.  Banks Monster Exhaust systems are 100% stainless steel and streamlined with heavy-wall tubing and constant-diameter bends.  Finished off with Banks’ proprietary CoolCuff exhaust tip technology, this is a meticulously designed & tested DPF-back system that actually delivers cooler diesel exhaust gas temperatures. It also cuts back pressure by up to 57% and has air-flows up to 80% better than your stock Duramax exhaust.  And of course no Banks Monster Exhaust or Banks Monster Sport Exhaust would be complete without an impressive 6″ rolled edge polished-stainless steel tailpipe.  It’s double-walled design features a 1/2″ air gap preventing heat from tarnishing its mirror finish.  The 4″ Banks Monster exhaust sounds great too, with that proven deep aggressive exhaust note diesel enthusiasts crave.

Want to increase your diesel fuel economy?

March 5, 2012

Fass lift pumps are a great way to increase your engine performance and diesel fuel economy by removing air and water from your fuel. It is well known that as your truck moves the diesel fuel in your tank is constantly in motion. This creates multiple problems with fuel delivery to your engine. While the injection pump draws fuel from the tank it’s creating a vacuum that produces fuel vapor and as the vehicle is in motion it creates fuel vapor that is mixed with the air. Resolve that issue by installing a FASS Lift Pump from Parley’s Diesel Performance and as a added bonus you will get higher power and reduce injector tip erosion. Typical No. 2 Diesel Fuel already consists of about 10% air. That issue is compounded by dirt and other debris that can be found in a diesel fuel tank. A FASS Lift Pump will address these issues head on by meticulously filtering out such problematic air & vapor (along with other contaminants in the fuel) before it reaches your truck’s injectors. Knowing about these latent dangers in the fuel at the diesel pump, can you really go on feeding it untreated to your truck? We at Parleys Diesel Performance strongly advise against it… and believe a FASS diesel lift pump is an excellent diesel performance upgrade choice. Get the most out of your diesel engine and your fuel dollar with a FASS fuel pump from Parleys Diesel Performance.
