Audi S4 B9 und S5 F5 2016 onwards: SPORTS EXHAUST SYSTEM

  • performance augmentation for the Audi S4 B9 by 13.1 KW and 4.6 NM *)

  • complete system behind catalyst with ECE homologation
  • rear silencer for original exhaust flaps

The Audi S4 B9 and the Audi S5 F5 come as sporty as ever and that was the reason for us to develop an equally sporty stainless-steel exhaust system. In addition to the sports exhaust system for the Audi A4 and the Audi A5, this system now complements our product range for Audi model.

We also included the sporty features and have chosen adequate sporty tailpipe variants. Besides the „Quattro E“ tailpipes (rear silencer with double tailpipe LH+RH 2x Ø 90 mm, with inwards curl, cut obliquely at 20°) there is also the „Quattro RACE Carbon“ tailpipe variant (rear silencer with carbon fibre double-tailpipe LH+RH 2x Ø 90 mm, with RACE look) available.

The complete system behind catalyst consists of two adaptors, one front link pipe and the rear silencer. The original actuator and the original exhaust flap control are used with the rear silencers. It is only possible to mount the complete system.

The sporty look of our BASTUCK sports exhaust systems is as usual matched by a deep and sonorous sound. The package is rounded up by a performance augmentation. For the Audi S4 B9 the latter is 13.1 KW and 4.6 NM *) in comparison to the original system.

*) Ref. vehicle: Audi S4 B9 260 KW / 5400 rpm, input measurement: 260.8 KW / 511.3 NM; measurement with sports exhaust system 273.9 KW / 515.9 NM, increase of up to 13.1 KW / 4.6 NM
