Picture 1 of 4

Description

Designed to work with the Zstory exhaust line*, this silencer, similar in looks to other, after-market Z muffler is unique in being supplied in 201 (Austentic) 1.25mm stainless-steel and can be quickly fitted to any S30.

Classed as ‘Street’ because it is more noise-friendly than the other muffler versions, it has the added advantage of reducing decibels sufficiently (when fitted together with a resonator) to pass most track-side noise tests. Zstory strives to adapt to ever-decreasing circuit noise limits !

Neatly tucking up under the body, it provides a discreet profile and classic look with rimmed edges as was supplied +45 years ago !

It comes with all necessary fittings ; clamp and straps and Zstory holds stocks of all parts in case of later street/road /competition damage or loss.

* will fit on the end of any 2.5’’ exhaust line or 2’’ with an adaptor (2-2.5’’)

  • Benefits

    Zstory has chosen its current diameter to be the optimum for the majority of (normally-aspirated) engine applications ; big enough to exit the gases quickly and easily at high engine revolutions, small enough to reduce the dBs and still sound great!

    The interior dimensions also optimise the sound-deadening without compromising performance.

    Seperate from the ‘S’-pipe to allow  for:
    – easier initial fitting
    – partial dismantling for easier servicing under the car – brakes, bodywork, diff and suspension.
    – the replacement due to accident damage, especially rally and slammed-street cars

    ⇒ Dampens down the overall noise limits for those who require it whilst keeping the awesome inline six sound.
    ⇒ Solid T-bolt clamp for a secure connection
    ⇒ Stainless-steel (201 austenitic 1.25mm) ensures a long life – fit and forget !
    ⇒ Complete kit which fits all S30s – all parts included for home fitting
    ⇒ Snug, high fit (rally and slammed Zs !) – low systems look ‘untidy’ especially from the side
    ⇒ Great classic, power-look for your Z !
    ⇒ Can be removed and swapped at any time for another Zstory muffler version

  • Dimensions

    ⇒ Interior tube diameters : 1x63mm / 2.5’’ entry and 2x50mm / 2’’ internal and exits.
    ⇒ Entry pipe = 63mm / 2.5’’ diameter (with 67mm sleeve) 110mm long
    ⇒ Box = 350mm long and 240mm wide x 110mm
    ⇒ Exit pipe = 1x63mm / 2.5’’ diameter (200mm long)
    ⇒ Total length = 660mm (front of entry pipe to upper end of exit pipe)

  • Applications

    Zstory exhaust systems are currently fitted to numerous competition cars – they have passed FIA homologation scrutiny but many more street, fast road and track-day versions also.

    It accompanies a wide range of engine sizes and states of preparation from L20As to the biggest strokers.
