AUDI RS3 8P Sportback QUATTRO 2.5 TFSI (340 Hp) 2011 -> (Ø80mm system) (with valve)

The exhaust system for the Audi A3 RS3 Sportback QUATTRO 2.5 TFSI is composed by a turbo downpipe kit with a metallic cat (200 CPSI), e centre section (available in resonated or unresonated versions), and a rear exhaust fitted with a bypass valve.

The valve, pneumatically controlled, is compatible with the OEM control management system.
When the valve is open the exhaust becomes a straight pipe, when it's closed the gas flow passes through a direct flow silencer.
The performance remains the same in both modes, and better then the stock exhaust.

The catalytic converter, as in the Supersprint tradition, is replaced by a HJS metallic unit with 200 cells per square inch. It's much more efficient and free-flowing but at the same time offers an optimal reduction of pollutant gas.

The downpipe must be fitted with the rest of the system. There are two options available: the centre pipe is the louder one, while the centre exhaust is a milder choice, to keep the comfort levels closer to the stock system but with a sportier tone.
If you're looking only for a more involving and sportier exhaust tone and don't want to replace the downpipe, the "cat-back" setup is recommended. It's composed by front pipes for the stock cats, the centre pipe and the rear exhaust.

Following the very long Supersprint tradition (est.1955), our main target is not to change the nature of the car, loosing comfort in the process, but to make the engine note more pleasant and characterful, without being excessive, but even more important, to increase the performance. We still offer a louder, more aggressive setup for enthusiasts.

The look is the perfect match of sportiness and class, with oval endpipes 90x70mm in polished black finish to match the "Black-Line" spec. They are perfectly integrated in the bumper line, for a sporty but still elegant result.
