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.

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.

Diesel Performance – Miracle or Snake Oil

March 6, 2008

There are so many products out there that just seem to be too good to be true and there are too many people out there that are more than willing to take advantage of another’s lack of knowledge.  There are also sooo many out there that are willing to play on peoples emotions; you know, the whole “You can have amazing results for practically nothing, and for only minutes a day at no cost to you”.  We’ve all heard it before.  So what makes diesel performance parts, like a chip, or a cold air intake, or an exhaust any different.  You might ask yourself, “Can adding something that small to my vehicle produce as great results as so many people tell me they do?”  Or will these items really pay for themselves in the form of increased diesel fuel mileage, and reduced wear and tear on my vehicle?  It is these questions about these products that I am going to address and at the same time educate, because knowledge is power my friends.

If you were to modify a gas engine for performance, you would be required to install a different camshaft, bore out the cylinders to increase displacement, install high compression pistons and heads, increase fuel intake capability by installing a larger carburetor or injection system, adding a turbo charger or supercharger, adding a chip, and enlarging the exhaust system.  But then you are still restricted by emission control systems.  On the other hand, diesel trucks and cars are mostly turbo charged, and they already run at a higher compression ratio.  Whereas on the gas vehicles you would have to make those changes.  If you were to make those changes to a gas engine you would truly have a ground pounding beast, but would lose every day driveability.  The diesels on the other hand, are nice to drive around even with considerable modification.  With a cold air intake, a diesel chip, more efficient injectors, and a more open exhaust system, the diesels are still a nice ride, but when you really give it the gas, all heck breaks loose.  There is enormous power without reducing driveability.

Because of the nature of diesel engines, they are designed from the factory to withstand much higher compression ratios than a gas engine.  The diesel fuel combusts when it is compressed to a certain point whether or not there is optimum air. By simply shooting more fuel into the combustion chamber you can make more power. When you then improve the air ratio & timing of the fuel — you can make dramatic power and also improve engine efficiency.  Gasoline requires a spark to ignite it & must have the appropriate mixture of air to burn properly.  Also, there is also a lot more energy in a given amount of diesel fuel than in an equal amount of gasoline.

Below is a break down of the most popular modifications and explanation of their benefits.

1. A cold air intake is sealed away from the hot engine air, and is located where it can take in more air.  Cold air intakes are equipped with a filter that can take in up to 300% more air.  Cold air takes up less space, so there can be even more air, all that air helps to burn all the fuel providing more power and better fuel economy.

2. Diesel chips make alterations to how the fuel is delivered to the engine, making it more efficient and more powerful.

3. A bigger exhaust or a mandrel bent exhaust (keeps the tube round, and the size constant) improves exhaust flow. Getting exhaust away from the engine is just as important in combustion as getting air into the engine. There are exhausts now that will even vacuum exhaust away from the engine, making it so that the engine doesn’t have to do that work.

All of these modifications add to the fuel economy of the diesel engine, over time they will actually pay for themselves in gas savings, and will continue to keep your money in your pocket for years after they are paid for. Diesels are the wave of the future and more and more economy vehicles are being produced in diesel versions because they are capable of so much better economy. – Nathan Young

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.
