Super Medalion Hyper Spec Bred from race technology, designed for street-level performance, and geared for clean styling, take the performance to the next level. With an extensive history in developing exhaust systems, the Super Medalion Hyper Spec is an ideal combination of a free-flowing straight-through design for a balance of performance, durability, and style. Tanabes highly accomplished Research and Development team were able to extract the maximum power potential of each individual exhaust application. Clean sporty exhaust note throughout the rpm range. Simple, straight-through main muffler minimizes backpressure. Constructed of highly polished stainless steel, the Super Medalion Hyper Spec has performance with style. All Super Medalion Hyper Spec exhaust systems have a simple big-mouth style 115mm (4 1/2in diameter) or 100mm (4in diameter) exhaust tip that fully accentuates the polished oval muffler can.

Featuring mandrel bends, the Super Medalion Hyper Spec is 100 percent SUS304 stainless steel, 1.2mm thickness piping, for maximum weight reduction and optimal durability. Stainless steel is also used throughout the entire system from the exhaust hangers to the main muffler canister for enhanced appearance and increased resistance to the elements. 2.5mm or 7mm flanges are used throughout the exhaust for the various temperature sections. Argon welding is used on all of the stainless steel components. The highly polished finish of the main muffler canister compliments any vehicle"s appearance. The Tanabe manufacturing facilities takes pride in being at the leading edge of top-notch quality construction and technological development. Our products are constructed in accordance to the industry manufacturing standard of ISO9001 (International Organization for Standardization 9001) Certification thus placing stringent quality assurance controls in place to ensure only the best. Race proven straight-form design allows for a minimum amount of bends for maximum performance. Mandrel bent pipes are used to optimize exhaust flow. After thorough research, the densities of the packing material are calculated to Tanabes own specifications for the aggressive deep exhaust note.
