Leading evidence: 'Check with ducati they were 650 notes' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'of the chinese ones' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Check with ducati they were 650 notes' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I recently had some SS ones from Design911 fitted (supplied by the former owner FOC, thanks!) and there is a definate reduction in noise (I have non-Gundo Dansk boxes).

A friend told me he'd fitted a Chinese copy for 100 quid so I did likewise.

All being fitted on the 10th March along with some refurbed (aluminise coated) cats.

The PO fitted some nice shiny stainless manifolds to my car.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

anyone taken off oem manifolds and run these with say a top gear exhaust and 200 cell cats?
sth like this:
https://www.ebay.co.uk/itm/STAINLES...e=STRK:MEBIDX:IT&_trksid=p2060353.m1438.l2649
I think I read someone has been running them for a few years with no issues and some perf gains
looking at the Dansk boxes earlier and the piping looks shagged already around the bends and thinking just go top gear SS all the way
I read on here that someones Dansk system lasted them a few years tops then was junk!
I put the Turbo version on my car (probably all made in the same factory) and I can't fault them for the money. I have kept my originals also should I ever need to refit. I would say go for it and treat yourself to some nice Ti bolts/studs too. :thumb:
We all cast a suspicious eye over cheap Chinese copies. And not without foundation in a lot of cases.
I run a Ducati 1098R track bike and I holed the rad one day. When I checked with Ducati they were 650 notes!! A friend told me he'd fitted a Chinese copy for 100 quid so I did likewise. And it's been absolutely fine.
I had the original rad reconditioned and now carry as a spare :thumbs:
I recently had some SS ones from Design911 fitted (supplied by the former owner FOC, thanks!) and there is a definate reduction in noise (I have non-Gundo Dansk boxes). The old set of manifolds droned between 55-75 so badly that my wife didnt want to drive in the car with me. Now we can actually have a conversation, and a decent snarl comes out over 3.5k RPM's which is perfect (for me)
As Norfolk & Idea said - we're all suspect of the CHinese ones, but some stuff can be the same or better than the original's.
have ordered up and will give em a try. thanks for the inputs chaps.
you do need to buy head bolts as well
Porsche OEM part number is 900 378 131 00 and 12 of em.
m8/28 standard fitment so most places should carry them and not have the P tax.
snakes alive. some shiny bits have turned up. going on next week and will report back on any sound change or performance improvement beyond the placebo!
I bought the toyosport manifolds to go with some new 'Predator Styling" backboxes sold through ECP which are in fact DesignTek Supremacy boxes. Rang the company and the chap I spoke to said they make them for DesignTek (which is a design911 brand isnt it?) under licence.
All being fitted on the 10th March along with some refurbed (aluminise coated) cats. Will post some pics up when done.
The 'cheap" manifolds look great, neatly welded, and confirmed by XRF that the material is as advertised (correct composition of substrate and weld wire) etc - can't comment on fitment yet...will pop some pics up when done.
Nothing wrong with material from anywhere so long as it's correct!
This is a source reference. Confirm exact model applicability in the original material.
