Dynaflex Exhaust

Dynaflex at Raney's

Dynaflex Exhaust Stacks provide a seamless appearance with an unmatched shine that withstands the test of time, because nothing looks sweeter than some chromed-out semi truck exhaust pipes on a Big Rig. Arguably the most noticeable aspect of a decked out Rig, semi truck stacks can be the focal point of your truck or the crucial element that compliments the rest of your design. However, exhaust stacks are more than just bright, shining stacks of chrome capable of bringing a tear to your eye; they can also aid in the performance of your truck—and that is a beautiful thing. This boost in performance from Exhaust stacks is subtle—unlike their bellowing roar—only slightly improving fuel efficiency and engine performance but still more than making up for its cost in the long run.
