Remus Audi S1 Performance Exhaust System

Audi’s S1 had a somewhat daunting task when it was launched back in 2014; it had to go toe-to-toe with the likes of the mighty Mini Cooper S, the Renault Clio Renaultsport and the Fiesta ST, and it had to do it all while wearing the same badge as the flame-spitting S1 quattro that powered Audi to so much WRC success in the early ’80s! Fortunately the S1 has proved itself to be a mighty car and one more than fit to wear the iconic badge, and a number of aftermarket offerings have sprung up to cater for it, the latest being a resonated cat-back sports exhaust system with electronically controlled valves from Remus.

Augmenting their already impressive array of exhaust systems for Ingolstadt’s finest export, Remus’s latest offering promises to be one of their most popular products to date, managing to balance performance with a suitably aggressive note. The core of the system consists of a resonated 70mm stainless steel front section, leading to centre sports exhaust with matching diameter and a pair of integrated valves and electronic actuators. The system is crowned by a selection of dynamic quad tail pipes in a variety of styles and colours, more information on which can be found below. All component parts have been extensively noise and performance tested, and all conform to EEC regulations governing both emission and decibel limits.

Three distinctive designs of quad tail pipes are available with the new S1 cat-back sports system, each designed to both enhance the performance and the visual appeal of the vehicle that they’re attached to. All three are 102mm in diameter and all come with an adjustable spherical clamp, but buyers can select from either an angled or a straight cut trailing edge, or between chrome or carbon finishes, the latter options even coming with titanium internals.
As is the case with all Remus systems, the quality of the workmanship involved is second to none, well above that of offerings from other manufactures and even rivaling OEM levels of fit and finish. Extensive testing of the system on Remus’s own development cars has revealed a noticeable increase in performance across the rev range, plus the aforementioned exhaust note that manages to be aggressive without ever becoming overpowering or obtrusive.

Remus exhaust systems offer performance benefits thanks to their careful design and carefully honed gas flow properties, but owners of Audi S1s can take advantage of one of the company’s other significant developments, the Powerizer. Designed for those seeking more performance from their car without having to go to the trouble of extensively modifying their engine internals, the Remus Powerizer can boost peak power by as much as 25% and torque by a hefty 20%. These amazing improvements are achieved thanks to the Powerizer’s ability to toggle the engine management parameters in real time, optimising the nature of the map multiple times per second in order to ensure peak gas flow at any given time.

There’s an added benefit to the Powerizer, one that perhaps isn’t as obvious as the performance advances, and that’s improved fuel economy. The added torque created lower down the rev range means the engine doesn’t have to work as hard to propel the car along the road, resulting in improvements in MPG. Remus’s trained technicians optimize the Powerizer to suit the needs of the customer, though the instructions included with each kit allow for it to be adjusted at a later date should the need arise, and all by simply pushing the clearly defined buttons on the control unit.

Finally there’s the Remus Responder, another innovation that’s been designed to improve the driving experience and complement the firm’s exhaust systems. As the name implies, the Remus Responder improves throttle response by adjusting the accelerator pedal output signal, resulting in noticeably reduced response and reduced lag when when applied cars with an automatic transmissions. Easily and swiftly installed between the OEM pedal sensor and the OEM connector, the Remus Responder can be unpacked, fitted and up and running in minutes, and all thanks to the plug and play technology at its very heart. The Responder operates using sophisticated adjustable programming profiles, technology that can lead to improved fuel consumption and more efficient engine running, while the four user-selectable and customisable performance settings give drivers greater freedom to tune the system to their specific needs.

The Audi S1 has already staked a claim as one of the all time hot hatch greats, a reputation that’s sure to grow as these cars become more commonly modified and embraced by the aftermarket tuning community. The fact that Remus has already designed, developed and produced a complete sports exhaust for this relatively recently launched model serves to highlight how seriously they take their work, with further Audi-based product launches already in development.
