Awesome, it is great to see them up. Thanks again

Im liking the manifold, do you have abreak down of how much each section costs? Will that manifold for example fit onto an existing system or will it only work on your system? That manifold looks like a lot less time has gone into it (in a good way not negative) which should relate to less labour costs and a cheaper manifold than current options. Fingers crossed!!

I have spent a lot of time with mike I have given him several different manifold to mimmick these are weaponR, piper, tms & tullet I insisted that what ever design he came up with, it would have equal length primaries. And be able to fit standard flange

Nice looking bit of kit. Will there be warranty on this product?

YES

[Noodle1791]

This is getting exciting!! Me like!

[davemate]

I will be seeing mike this weekend and I will get a breakdown of costs to put up here.

There is a long running argument on here about the design of the manifold.

Sure it makes commercial sense to design the 'zorst around a standard manifold, but wouldn't it make sense to optimise a design that doesn't have to fit to a standard OEM manifold?

AFAIK all of the manifolds you mention have been reverse engineered to fit previously developed exhausts?!?

I could be wrong though.

Completely right & correct


when mike builds syatems for me the flange location is the last thing on our mind

but there is a gross shortage of retro fit aftermarket manifolds several have tried


If one whats a bespoke system one can have it
but
if one wants a superior manifold that fits oe one can also have it

I thought that might be the case.... If Mike sells manifolds, why not offer (say) a 'standard' 4-2-1 alternative with optimised primary length? I'm no expert (the price seems pretty bloody good) but im struggling to see why I would want a replacement system/manifold which seems compromised at the business end?!? I dont think I'm talking bespoke here, just a replacement manifold and back system that isnt restricted by the OEM manifold/downpipe connection position

[davemate]

I wanted something to fit into the standard space and didn't want to cut the boot... I think that the weapon r one needed this.

I asked him for a mani for standard flange
Why don't you ask him for a 4,2,1

I know he will oblige

I'm sure he will.

I'm just not getting this bit:-

^^^ makes no sense to me

[davemate]

Mike is making atom's rear subframe and in addition to this the engine will be mounted quite differently. I think is implying that performance and function of the system will come first and then working how to mount it etc will then be worked out second.

[Mike (Cliffie)]

Pardon the ignorance but does it matter where the flange is if the system is (or has) to follow the OE path or is it a case of making longer primaries?

[The Batman]

whats the db read out? also the manifold doesnt look very equal from the picture?

[FLD]

whats the db read out?

Thats the million dollar question. I've yet to find one that is satisfactory despite manufacturers claims.

I am testing this at the weekend to get some final figures now that it has all settled in I have done a few hundred miles on the new system now and given it a fair amount of grief to test. So drive by, and static will be tested. What is the set of standard tests by the way, 3/4 full revs at 1 metro 45 degrees I know is the static test, but I don't know the full test for drive by??

[techieboy]

but I don't know the full test for drive by??

Not sure there is a standard for drive-by's and it's down to the tracks.

At Bedford they theoretically measure it at 20m (hence the stupidly low looking number), although I'm sure at least two of the four sound monitors are much closer to the track than that and are placed where you're naturally on full throttle.

Donington has a monitor suspended above the circuit and it's much closer - more like 3 or 4 metres.

Not sure about Goodwood or Combe that are other tight ones as I haven't wasted the money trying.

Throw in some random atmospherics and different drivers going past them in different gears at different rpms and it all seems to turn in to random luck.

[davemate]

Just measured at 80db idle with 92db at 4500rpm. Will test the drive by as well today
