With all the performance parts out there in the diesel industry, knowing what you need, and why you need it can often be challenging. The staple of the diesel industry is still intakes, exhausts, and tuners, but with so many choices out there it’s often hard to choose a part that you know you’ll be happy with. Often there are customers that will ask, do I even need an exhaust system, or an intake? Well, that depends what you’re looking for.
Virtually all modern diesels are turbocharged, and getting air in and out of the engine is very important. The factory does a good job of designing intake and exhaust systems, but there’s always room for improvement. When building a truck, engineers have constraints like vibration and noise that the average enthusiast may not worry about. When we put an intake on an otherwise stock ’97 Dodge, the first thing we noticed is that we could actually hear our turbo doing some work! While it may seem like a little thing, the improved sound alone was worth the price of admission.
The same goes for exhausts. Factory exhaust systems are often both quiet and heavy, while aftermarket units let the engine breathe a bit more, as well as producing a louder note. There’s also an extremely wide variety of tips and exhaust stacks, and polished materials to choose from. Often times an aftermarket exhaust is mandatory when turning the power up on a truck.
Which brings us to tuning. As long as the truck is at the factory power level, intake and exhausts probably won’t add much power; maybe 5-10 hp. But, when the truck (and or boost) is turned up, the gains can be significant. We’ve seen nearly a 30-hp gain on tuned 6.4L Fords from an aftermarket intake, and a good 20 hp from some exhaust systems. There are some vehicles (like first generation Dodges) that have horrible exhaust systems, and can really benefit from an upgrade.
So bottom line, do you need these parts for your truck to run? No. But, if you don’t have them, you’re closing your vehicle off to future modifications, as well as leaving power and sound improvements on the table. Not to mention improving underhood and exterior looks. If you’re unsure where to start, Pure Diesel Power is always there to help, and we can guide you through a tuner/intake/exhaust package that perfectly fits your needs. The bottom line is that intake and exhaust systems are still some of the best bangs for your buck, which is why they’re a first choice for so many Cummins, Power Stroke, and Duramax enthusiasts.
