Heads up owners of 964 Carrera, RS and Cup models. Apart from being lucky enough to own a bona fide modern classic the likes of which we'll never see again, you can now up your P&J'S aural ante with Cargraphic's new sport centre silencer. Fashioned from T-304L lightweight stainless steel, the new exhaust features innovative 'pressureless' exhaust flaps. The upshot is low-noise start up in contrast to systems that rely on vacuum pressure to close internal flaps and can generate an unwanted din. On the move, the system opens up to unleash a fuller range of flat-six sounds than the factory silencer. Cargraphic says the silencer also offers reduced back pressure and thus releases a little extra power and torque. Prices vary according to precise application, but the starting pre-tax sticker is €2,374. Find out more from cargraphicts.com.
