Extreme rear silencer delete for second‑generation hot hatch heroes R56 and R57
Turn up the drama with Cobra Sport’s loudest setup for the 1.6 turbo models. This straight‑through rear section removes the back box for a raw, motorsport soundtrack that commands attention on track. If you are chasing maximum flow and a fierce tone, this is the one.
Compatibility: works with Cooper S, John Cooper Works and GP2 variants. Built in 63.5 mm 2.5 inch pipework and configured from the catalyst backwards, it replaces the mid pipe and tail section to unlock serious sound and response.
Why enthusiasts choose this system
- Rear muffler delete and straight pipe layout for an aggressive, race‑car character
- Cat‑back design replaces centre and rear sections for improved flow and razor‑sharp throttle response
- Choice of centre section: resonated for a deeper tone or non‑resonated for maximum volume
- Designed by Cobra Sport for a hard‑edged, track‑focused soundtrack
- All fittings and gaskets supplied for a hassle‑free install
How it sounds
Back box deleted means extremely loud. Expect an aggressive crackle on overrun and a fierce bark under load. If you want something a touch calmer, choose the resonated centre option which adds a mid silencer while keeping a purposeful note.
Measured noise levels
