Thanks to the reflection - the construction of the ULTER sports muffler, a reduction in exhaust back pressure of up to 35 to 85% is achieved, which can mean an effective increase in performance of 3 to 5% depending on the type of muffler and vehicle. We rely exclusively on the highest quality. For you, this means that you are buying sports exhausts, exhaust tips or exhaust pipes that are characterized by their longevity. Material fatigue after a short period is excluded. The highest quality also means the greatest precision in fitting. Each piece in our segment is manufactured with precision and fits 100%. Ultimately, of course, you also see the quality.
