Description: This Flo-Pro Twister Muffler (part numbers 51299 & 51600) is a must - have universal add - on for any 4' or 5' exhaust system. It fits any truck with such an exhaust setup, and Flo - Pro Exhausts are generally designed to fit all wheelbase and cab configurations. The Twister muffler uses a high - flow dual - path system. It keeps your exhaust quiet for street use without restricting the flow like the OE muffler. It meets most track requirements and acts as a resonator in diesel applications. Flo - Pro's tests show an insignificant power loss when adding this system. Features: Fits any 4' or 5' exhaust. It's 18' long with a 5' round body, made of aluminized steel. It has a high - flow, continuous spiralized design. It reduces drone. The continuous spiral design cuts down turbulence for better flow and more HP compared to other spiral baffle designs. The dual - flow path cancels noise and creates a vacuum effect to speed up the exhaust.

Using your Flo - Pro Twister Muffler is easy. First, make sure your truck has a 4' or 5' exhaust system. Then, simply attach the muffler according to the standard installation procedures. When driving, you'll notice a quieter exhaust on the street and better performance. For track use, this muffler meets most requirements. As for maintenance, check the aluminized steel body regularly for any signs of rust or damage. If you see any issues, clean the affected area and consider applying a protective coating. Also, keep an eye on the connections to ensure they are tight. If you experience any unusual noise or a change in performance, it might be time to have the muffler inspected.
