Although the 4.7L PowerTech V-8 performs admirably, it is no powerhouse. With that in mind the nearly 10 horsepower and 15 lb-ft of torque added by the True Flow intake and Gibson exhaust are noticeable. Gibson prefers to improve both power and sound, and the Superflow muffler in our kit sounds just a bit louder than factory with a nice bass tone to it. It’s just enough to be noticeable and ideal for your everyday driving needs. Since the intake is still breathing from the stock air box, it retains all its over-engineered factory conveniences plus the benefit of a direct path of air now; all the power with no suction noises under hood. With Tom McWeeney of Kustoms Inc’s handy paintwork, our Dodge can now roll down any boulevard not looking the under-optioned sibling it is. And the Boss wheels wrapped in Nitto tires bring not only looks, but also a nice jump in performance. Corners can now be handled without all the excitement of the stock sidewalls nearly folding in half. Driving down the freeway is great too; the Nitto tires are night and day difference in the noise department. All in all we managed to keep a low budget, add smart options, and do it all for a low price that brought high driving value to the Durango.
