The BCS Valveless system is our acoustically tuned, dual tone Turbo back system for the Skoda Octavia Vrs 2.0Tsi , providing you with the maximum possible full-time audible thrill from your Octavia. The system has a greater audible volume than the Cat Back 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 Turbo Back system was developed to be a true valveless dual tone exhaust, through extensive research and development we were able to incorporate our acoustic tuning technology 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 3 variants a Wrc, Sport & Prestige sound profile, tailored options depending on desired exhaust note. Our Wrc 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 Sport variant is our mid range sound profile, giving you the best of both worlds, it's still got the motorsport inspired raw under high load as well as the discreetness of the prestige system when driving sedately. Our Prestige variant is our quietest system designed for those wanting an OEM+ note, a discreet growl turning heads when accelerating paired with a stock sound when cruising.  

As with virtually all of the TSi engined vehicles, there is very little performance gain to be had from the cat back system on its own, due to the incredibly restrictive downpipe and  OEM cat. However, by opting for our unique downpipe and high flow cat the power potential will massively increase, firstly with an initial 22bhp kinetic, and then once mapped all the TSi 2.0 MQB Engine can achieve in excess of 400 bhp with our full turbo-back system and 100 Cell road-legal cat
