Who Is Supersprint?

Since 1955, Supersprint has been manufacturing high-performance automotive exhaust systems, with the largest range of products in the world. Right from the start, the company’s goal was to consistently offer the highest quality materials, superior finishes, and unmatched product lineups with a keen focus on designing, researching, and supplying the best-performing exhausts all around the globe.

Many competitors choose to sell the same universal exhaust parts with only minor changes for drastically different vehicles. The consequence is a system that is not optimized for your particular vehicle and application, resulting in poorer performance than the OEM system. Supersprint, on the other hand, approaches each individual vehicle exhaust application as a custom design. By avoiding “cookie-cutter, one size fits all” exhaust systems, Supersprint is able to tailor its products to deliver consistent performance gains and incredible sound characteristics.   

Trustworthy Manufacturing

Supersprint’s commitment to excellence involves every stage of development. Each exhaust system has been thoroughly researched, intricately designed, and rigorously tested to ensure additional power gains and overall performance enhancements. All Supersprint designs are validated by extensive testing methods, which includes hours on the dyno, to guarantee the best possible product before it hits the market. No other race team engine testing department or car/exhaust manufacturer out there boasts the same performance evaluating experience as Supersprint. 

To put it into perspective, Supersprint’s dynamometer performs well over 1,000 test runs a year on a full range of automotive brands. The brand works tirelessly to evaluate each automaker’s sports car models and all of the available engine options. What’s more, Supersprint is often called upon to provide closed-door dyno testing for some of the world’s top racing teams. This additional information helps the teams prepare for world-class rally and road racing events. The experience also provides the Supersprint staff with a database of powerband information that is unrivaled in the industry. The vital information and power figures play a large role in the design and production of each individual exhaust component and complete system that Supersprint manufactures. 

Commitment to Quality

Supersprint exhaust systems are manufactured to exact industry-leading standards of excellence. The company was awarded quality certification ISO 9001 by the FAKT, which guarantees the highest standards of research, development, and production. This certification attests to the fact that each Supersprint product fulfills stringent quality control requirements as determined by the latest E.E.C. guidelines. Every raw material batch, from stainless steel tubes to rock wool insulation packs, is carefully selected and examined prior to its use.

When you look at Supersprint products, you can immediately see the attention to detail, quality materials, precise welds, and superb finish. It is not hard to see how or why Supersprint produces one of the best automotive exhaust systems available on the market, in the world! It’s all there in the appearance, sound, and performance of the system, which is guaranteed to last for years to come.
