VW Golf 2.0L TDI Exhaust System

May 19, 2012

Based on the success they’ve had with their popular 3 Inch Stainless Monster Exhaust for the 2.0L CR Jetta TDI, we’re pleased to announce that Gale Banks Engineering has now released a Banks Monster Exhaust for 2010-2012 VW Golf TDI’s.

Made from stainless steel, the CR TDI exhaust system retains your emissions control equipment while eliminating all remaining factory restrictions.   It removes your muffler, and replaces the stock dual exit tips with a massive high-polished 304 Stainless steel tip.  This exhaust is a great starting point to help take your Golf to a whole new level of diesel performance. More quickness off the line, more power throughout the RPM range, less heat, and better fuel economy … all in one simple bolt-on package.

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.

No Def Defined

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.

2011 2.0L VW Jetta TDI Exhaust System Upgrade

August 26, 2011

Parley’s Diesel Performance is pleased to announce that AFE has released their stainless steel Catalytic Converter-Back exhaust system for the 2011 Jetta TDI.  AFE had previously made available the same style system for the 2011 Golf 2.0L TDI exhaust and all the early reviews on that system have been positive, so we expect good things for 2011 Jetta TDI owners who choose this system to upgrade their cars.

The exhaust note is a bit throatier than stock, and the dual 3 inch double-walled polished T-304 Stainless steel tips look really clean and aggressive.  The exhaust system is fully mandrel-bent as you would expect, and the hangers line up well for a good clean installation.

Many cat-back diesel exhaust systems don’t require any cutting of the stock pipes for installation, but this kit does.   It’s impossible to clear the rear axle when removing the OEM exhaust without making the cut.  We just wanted you to know.  If you’re interested in upgrading the performance of your 2011 Jetta TDI (including Sportwagens), we recommend pairing this TDI exhaust upgrade with AFE’s 2.0L Jetta TDI Intake system and a 2011 TDI Performance Module from Diesel Power.

One last note – this exhaust system is legal in all 50 U.S. states because it retains all of your emissions control equipment.

Cummins Performance, the Best in the Biz

July 1, 2008

The Dodge Cummins diesel is known for its diesel fuel mileage and ability to be built up for power…. and known for its transmission for different reasons.  The Dodge Diesel trucks are the favorite of anyone that is looking for fuel economy in a diesel and doesn’t have a brand preference, because the dodge gets the best economy of them all.  Even at that, things are tight with the cost of diesel and the hard times in the economy.  There are some things that can be done to make it even more fuel efficient.

The first thing that anyone is going to do to make their Dodge Cummins diesel more efficient for fuel economy and power is install a Cummins diesel chip, programmer or module of some sort.  Cummins performance diesel chips, programmers, and modules all do essentially the same thing.  They alter “timing” or when the fuel is injected; “duration” or how long the injector is held open to release fuel; or “pressure” which slightly increases fuel line pressure to put more pressure up against the injector and get a better atomization of the fuel.  Most chips, programmers or modules use a combination of the methods to improve engine efficiency.  Most chips, programmers or modules give anywhere from 1 to 5 miles per gallon increase in fuel economy, dependant upon driving habits and the truck configuration itself.  The gains for the 5.9L Cummins engines are pretty consistent, however, the new 6.7L Cummins diesels are different.  They have a new emissions control system with a diesel particulate filter that hampers performance and fuel economy.  Most chips give these new trucks about 1 mpg better fuel economy.

Another way to increase efficiency and power are air intakes and larger diameter exhaust systems. Cummins diesel intakes generally give about 1 mpg and exhausts can be anywhere from 1 to 4 mpg.  If you do a chip, intake and exhaust all together, you actually get a little bit more out of each item.  The nice thing is that all the add-ons give more power and pay for themselves pretty quick in the added fuel savings.  The newer Dodge Cummins diesels don’t really need an exhaust upgrade since they come standard with a 4 inch diameter exhaust from the factory on the 2004.5 model and newer Dodge Cummins diesel trucks.  Performance diesel exhaust changes that can be made on the 6.7L trucks is very minimal due to all the sensors in that exhaust system.  It’s nice to know that we have alternatives though.

How To Increase Diesel Fuel Mileage!

March 27, 2008

As of late we are getting a lot of people asking how to increase diesel fuel mileage.  With diesel over $4.00 a gallon and expected to go well over $5.00 a gallon this summer its no wonder why people are wondering how they can increase diesel fuel mileage.   Here are the things we have found that work best to increase diesel fuel mileage:

Diesel Performance Chip: Using a diesel performance chip is one of the easiest ways to increase your diesel fuel mileage, usually with about ten minutes or so spent installing a “chip”, you can increase your fuel economy by 1-5 MPG.  Some companies have actually released chips dedicated to increasing diesel fuel mileage including the Edge Mileage Max, Hypertech Max Energy and Quadzilla Max Mileage.

Diesel Performance Intake: Usually if you have already added a chip the next best thing to help increase diesel fuel mileage.  Diesel performance intakes allow your engine to breathe easier, which will help increase diesel economy.  You will usually see a 1-4 MPG increase.  Some of the best known performance intake manufacturers are S&B Filters, AFE and Airaid.

Water Methanol Injection: Now most people would recommend going with an exhaust system for your third mod to increase fuel economy.  We have found that when it comes to bang for your buck, the Snow Performance Water Methanol Injection Kits lower exhaust gas tempratures more and increase diesel fuel mileage better than an exhaust system.

If you have any further questions on how to increase diesel fuel mileage please contact us.

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
