Turbo Back Exhaust

Turbo back exhaust systems for Ford Powerstroke, Dodge Cummins, and GM Duramax diesel trucks always ship free at Parley’s Diesel Performance! We offer a complete selection of diesel turbo back exhausts in all the most popular materials from the best manufacturers in the business. Top brands like Banks Power, Magnaflow and MBRP make turboback exhaust kits that install correctly every time. Better looks, better sound, better fuel economy, and lower exhaust gas temperatures while towing are all yours – simply by adding a turbo back exhaust.


Why such performance and fuel economy gains with a turbo back exhaust system? It’s simple physics and engineering. The less work your diesel engine has to do to expel exhaust gasses, the better. Your stock exhaust system has multiple restriction points where the piping may reduce briefly from 4 or 3.5 Inches down to 2.75 Inches. Aftermarket diesel turboback exhausts are built with larger than stock diameters. Just as important as the larger diameters is the use of mandrel-bending machines. Mandrel bending is a process that leaves a constant pipe diameter throughout the entire length of the exhaust. This greatly eliminates restrictions, which means your engine can move that bad air out to the tailpipe easier than with your stock exhaust.

Whether you want a 4 inch, 5 inch, dual exhaust, T304 Stainless Steel, or simple straight pipe no muffler system, Parley’s Diesel Performance has you covered. Some of our more popular choices include MBRP’s 4 Inch and 5 Inch Performance No Muffler and Stainless No Muffler turbo back exhaust systems, often paired with an Aero Turbine Muffler. Dual Exhaust Systems are a popular choice with diesel enthusiasts who really want to show off their ride with pride. If high quality Stainless Steel Exhaust Systems get you all excited, Magnaflow offers 4 inch and 5 inch exhausts in three separate grades, each with a lifetime warranty. The Magnaflow Performance Series is their top of the line T304 Stainless Exhaust System. The Magnaflow XL Series is their mid-level Stainless Steel system. The Magnaflow Pro Series is their entry-level 409 stainless steel exhaust system, but don’t be fooled; the Pro Series is an outstanding value.



Many of our customers come to us and ask “should I get a 4 inch or a 5 inch turbo back exhaust?” The simple answer is to get whichever one you want. Realistically, unless you’re planning on exceeding 600 rear wheel horsepower, you’ll be just fine with a 4 Inch turbo back exhaust system. That being said, with today’s diesel trucks pushing almost 400 horsepower coming off the factory assembly line, adding 200 horsepower isn’t that much of a stretch. It won’t hurt you to have a 5 Inch exhaust system if you’re under 600 horsepower, and you have flexibility in the future if you get addicted to the power (trust us, it happens all the time) and decide to upgrade your diesel more than you originally planned. Whatever you decide, Parley’s Diesel Performance has a huge selection of turbo back diesel exhaust systems for every diesel truck. If you have any questions about which exhaust system is the right one for you, shoot us a quick email and we’ll steer you down the right path.
