Top 5 Turbo Back Exhaust Systems for 6.7L Powerstroke Diesel Trucks

Introduction to 5 Turbo Back Exhaust Systems for the 6.7L Powerstroke

Diesel trucks like the Ford Super Duty with the 6.7L Powerstroke turbo diesel engine are extremely popular for both work and play. One of the most common modifications owners make is upgrading the exhaust system. The factory exhaust is restrictive and replacing it with an aftermarket turbo back exhaust system can unlock more power and give your truck a much deeper exhaust tone.

In this comprehensive guide, we'll discuss what you need to know about 5 turbo back exhausts designed specifically for the 6.7L Powerstroke engine. We'll cover the benefits of upgrading, review 5 of the top exhaust systems, and provide tips for choosing the right one for your needs and budget.

Benefits of Upgrading to a Turbo Back Exhaust

Here are some of the key benefits you can expect from installing an aftermarket turbo back exhaust on your 6.7L Powerstroke:

• Increased horsepower and torque - By improving airflow, a turbo back system can add 15-40 HP and up to 80 lb-ft of torque.
• Better throttle response - Reduced backpressure improves turbo spool up.
• Enhanced engine sound - Aggressive exhaust tone can be customized with different muffler options.
• High temperature longevity - Quality stainless steel construction holds up better than factory exhaust.

Choosing the Right Exhaust - 3 Key Tips

Keep the following important tips in mind when selecting a new turbo back exhaust for your 6.7L Powerstroke:

1. Match the exhaust to your performance goals. More aggressive systems advertise the loudest gains but limit muffler options. Make sure the sound level achieved matches how you plan to use your truck.
2. Consider additional exhaust system upgrades like an exhaust brake, pre-turbo muffler, or cab noise insulation if harsh sounds are a concern.
3. Have a professional shop install the exhaust to avoid leaks. Proper fitment is critical to achieving expected performance improvements.

Upgrading the exhaust system is one of the best ways to unlock the performance potential of the 6.7L Powerstroke diesel engine. With so many options available from top brands, you can dial in the perfect blend of sound, power gains, and budget for your Super Duty truck.

FAQs

Do I need a tuner to see gains from an exhaust upgrade?

While a tuner will maximize your power gains, most users see improvements without one. Better flowing exhaust systems reduce restrictions to help your engine breathe easier.

What's better - a turbo back or straight pipe exhaust?

A turbo back is better for most users because it replaces the entire system from turbo to tip. Straight pipes just replace the muffler section and won't unlock as much power.

Will a new exhaust system cause my truck to smoke?

Upgrading your exhaust won't directly cause more smoke. But it may highlight existing issues causing smoke like bad injectors, low fuel pressure, or poor engine tune.

Is it difficult to install a turbo back exhaust at home?

Full exhaust system installs require some mechanical skill and the right tools. Most users have a professional shop complete the install to ensure proper fitment and alignment.

Will an aftermarket exhaust void my truck's factory warranty?

As long as the exhaust doesn't cause damage, it won't void your overall warranty. But replacing emissions-related parts may void coverage for related components.
