Supersprint exhausts are hand-crafted in Italy using only high-grade stainless steel. Supersprint engineers create model- or engine-specific systems with components, pipe diameters, and layout all considered specifically for each model. Systems are first designed as a whole, from the engine to the tailpipe, to maximize gains and produce a pleasing and sporty sound. Street systems meet European sound regulations while "Race" systems offer more volume for export markets such as the USA. Most systems are modular and can be built with or without resonators and/or sport catalysts. Whether for street or race use, Supersprint researches, designs, tests, and builds exhaust systems for real world power and long lasting, quality construction.
