280ZX exhaust

Having looked at this subject in depth today, I've come to the following conclusions :
1) the system to be prototyped will be based upon my Street-sport 1 5/8'' exhaust manifolds
2) the 2.5'' exhaust line will be conceived for a 2+2 with a shorter part in its length for the few 2x seaters
3) 2 silencers and with an aim to keep the noise level 'sporty' but comfortable for distances, town-driving etc
4) a single pipe outlet and exiting only on the left hand side
Sorry for any disappointments - anyone wanting a twin-outlet can cut the end off and stick their choice on; anyone wanting a rh-side exit can also modify my exhaust rear but it won't be easy and I don't see ANY advantage whatsoever, rather the inverse !
I expect to a have the prototype finished by the end of November for factory/workshop appraisal and thereby available to buy around Easter 2017. Later than expected and I wanted but that's life

....you don't Andy - you'd be better off with a 3" line and certainly not manifold !

Yes, thanks Mike - I won't be using one for the other but they are both two tiny pipes of 38mm internal diameter.

Firstly, thanks Huw for the photos and video - all info is useful.
Base parts sourced for the fabrication of the 280ZX prototype exhaust.
Evidently, we're looking to produce a circular centre box and oval rear where the shape is determined by the heat-shielding.

The prototype exhaust line is finally finished with :
*2-1 downpipe from the OEM cast-iron exhaust manifold
*2x seater and 2+2 versions
*fits early and late models
*2x silencers
*complete with fixing brackets
There remains to be defined which 6-2 exhaust manifold I'm going to use but I won't rule out two versions - one 'soft' and one 'hard' !

Getting there Sean. That tail pipe looks a bit long to me though.
What do you mean by 'hard' & 'soft' manifolds? Also, will you be able to fit one of you trick manifolds to the system at a later date if you decide to use the original manifold to start with??
Look forward to seeing the final product.

Thanks Huw - I'll double-check the tail-pipe but remember that it is aimed at every n/a model from 1979-83.
Soft....stock replacement and mild tune.
Hard - mid to high modification.......and if I had an OEM turbo manifold, I might be persuaded to produce a stainless one as well.
I believe that the above has just answered your question.

In this next batch there will only be:
5x manifolds and lines
5x downpipes and lines
And 2x of the former are already sold.
If these are all received well, in the next batch (Spring 2018) I'll be planning a lot more.

Both, for the same price, are available for 2x seaters and 2+2s - prices are set at :
Exhaust manifold and complete line (rear muffler included) : £920
Exhaust downpipe (from OEM manifold) and complete line : £732
Both suject to a 10% reduction for paid-up Z Club members.
Available from mid-August with a reminder that both exit on the LHside of the car.
