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.

Diablo Predator Tuner Review

September 12, 2007

A couple of months ago, my boss at Parley’s Diesel Performance asked me to put the Diablo Predator Programmer on my 2005 Dodge Cummins so that we could get some real world test and numbers as far as mileage gains etc.. There had been several of our clients who had purchased this diesel tuner from us and had been reporting increased diesel fuel mileage of anywhere from 1-4 MPG so we wanted to see for ourselves what it could do.

What’s Included:  Here are a couple of pictures of what you will see when you open the Diablo Predator package.  When you first open up the package you will see the Diablo Tuner, as you open it up you will see the Instruction manual as well as a promotional Ruler.

diablo_predator_2.jpgdiablo_predator_1.jpg

 Why The Diablo Predator?  A lot of our clients are interested in the Diablo Predator for the following reasons:

  • Economical- Compared to some of the competing diesel programmers like the Bully Dog Triple Dog  priced at $597.99 or the Superchips Flashpaq  priced at $499.99 the Diablo Predator Programmer is a deal at $399.95.
  • Great Performance Gains-  For my applications, 05 Dodge Cummins, there are three performance settings and those are 60hp Tow Setting, 100hp Performance/Economy Setting and 160hp Extreme Performance Setting.  In my opinion its great bang for the buck.
  • Increased Diesel Fuel Mileage-  Like I said earlier we had heard from out clients that they had seen gains of anywhere from 1-5MPG, with my truck I saw about the same range actually, some tanks 1MPG better and some tanks 5MPG better.  It just depended on how I drove it, of course.

Why Not the Diablo Predator?  I have really enjoyed the Diablo Predator during the time I have had it on my truck, how can you not enjoy 60-160 more horsepower right?  The main problem that I have had with the predator is:

  • No Over sized Tire Recalibration on the Cummins- If you drive a Duramax  it’s a different story but I would have liked to be able to recalibrate my speedo to get more accurate fuel mileage etc..
  • No Speed Governor Recalibration-  Who wouldn’t want to go a little faster right?

So in the end I am overall satisfied with the performance and mileage increase for the money with the Diablo Predator Tuner, if you are running oversized tires and have the money you might be better off with something like the Superchips Flashpaq.
