The BCS Valveless system is our acoustically tuned, dual tone Cat back system for the Seat Leon Cupra 2.0 TSi, providing you with the maximum possible full-time audible thrill from your Cupra. The system has a greater audible volume than the stock exhaust offering, however, with careful design and development we have created a system that ensures that any unwanted in-car frequencies are removed, leaving you with a perfect drone-free experience, together with our characterful pop and burble, free-revving sound. 

The BCS Cat Back system was developed to give a true valveless dual tone exhaust, through extensive research and development we were able to incorporate acoustic tuning into our system to retain the subtlety of cruising and under low load whilst offering the aggressive, characterful note when accelerating and under high load. Produced in 2 variants a Sport & Prestige sound profile, tailored options depending on desired exhaust note. Our Sport variant is our loudest variant engineered for a motorsport inspired tone when accelerating and under high load but remains subtle whilst cruising and under load low. Our Prestige variant is our quietest system designed for those wanting an OEM+ note, a discreet growl turning heads while accelerating paired with a stock sound when cruising.
