Zstory JDM mufflers

Picture 1 of 2

Description

Designed to work with the Zstory exhaust line*, this silencer is made from 201 (Austentic) 1.25mm stainless-steel and can be quickly fitted to any S30.

Named ‘JDM’ and commonly mistaken as being specific to the ‘Z432’ ; it was in fact optional on all Japanese domestic market (JDM) Fairlady Zs but OEM only on the Z432s !

Neatly tucking up under the body, it provides a discreet profile and timeless 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 pipe volume to exit the gases quickly and easily at high engine revolutions, small enough to keep the dBs reasonable at low engine revs 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.

    ⇒ 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 JDM racing look for your Z!
    ⇒ Can be removed and swapped at any time for the Classic version.

  • Dimensions

    ⇒ Interior tube diameters : 1x63mm / 2.5’’ entry and 2x50mm / 2’’ internal and exits.
    ⇒ Entry pipe = 63mm / 2.5’’ diameter (with 67mm sleeve)
    ⇒ Box = 380mm long and 150mm diameter
    ⇒ Exit pipes = 2x50mm / 2’’ internal diameters
    ⇒ Exit pipe max. lengths = 180mm long (top) and 150mm (lower) on the top of each tube.
    ⇒ Total length = 660mm (front of entry pipe to end of upper twin 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.

  • Option

    From 2017, whether 2x seater or 2+2, the Zstory exhaust line will be supplied without a rear silencer/muffler allowing you, the customer to choose your preference:
    – Classic : the single-exit version.
    – JDM : the twin-exit version
    – Street : the single-exit, baffled version



Don’t forget to look at the Classic silencer page in order to define your choice and please don’t hesitate to contact me for advice.

*this silencer will have an optional, quieter version (internally different – no external change) in 2017 as Zstory continues to adapt to ever-decreasing circuit noise limits.
