Milltek Valved & Resonated Catback Exhaust System w/ EC Approval for 8X Audi S1
Milltek Sport offers a range of catback systems, meticulously crafted for those looking to improve their vehicle’s sound and visual style. Designed for easy installation as a direct substitute for the original exhaust, these systems come in multiple options. Such flexibility allows users to customize the loudness of their exhaust and / or achieve a more aggressively tuned sound. Made from 304L aircraft-grade stainless steel, Milltek Sport’s catback systems are built to endure extreme conditions, providing both lasting durability and sustained performance.
Milltek Sport introduces the Valved & Resonated Catback Exhaust System with EC Approval for the 8X Audi S1, tailored for drivers who demand excellence in performance, sound, and legality within European standards. This system combines the sophistication of a resonated design, which offers a deeper, richer exhaust note without overwhelming noise, with the innovation of valved technology, allowing drivers to adjust the sound intensity for a personalized driving experience.
