One name that I haven't seen in this thread yet, is Longlife Exhausts. I haven't used them myself, but a number of people on the forum have done, with good results http://www.scimitarweb.co.uk/sgwrs/sear ... fe+exhaust

Long life are a franchise though - different standards and prices across the country.

Having said that, I have a longlife system on the K series SS1 and it looks REALLY well made. Interestingly, you can also transfer the lifetime warranty under certain conditions.

Here are some pictures of the ones from FWB 144H. The headers are not stainless, but the collectors and rest of the exhaust are.

I've had sets of the headers and collectors made in stainless for about £800. That was two years ago. I'd need to take them back and get another quote.
These were painted white for the dyno work but are now coated inside and out by CamCoat - http://www.camcoat.com/

Biggest gripe with these headers is fitting six individual pipes, but clearly they could be made on to an exhaust flange for each side.

Seal of pipe in collector is made using a thin wipe of high temp gasket seal.

Not sure the difference in price between normal steel tube and stainless would cover Camcoat treatment, but they do stay much cooler under the bonnet.

Camcoat say they can treat stainless but I've had it peel off on the Sabre collector which is stainless:

Maniflow came back to me , they don’t do them because they don’t have templates anymore , been thrown away . Although they do 2 different manifolds for early and late Gilberns guess that’s beacause they are sold through GIlbern Owners Club.

So options . Allington Gt is a possibility . Double S do them . And ScimitarV6 is looking into getting some made .

Here's another option.

I've just had lunch with Terry Cox and he reminded me that he took photos of my manifolds a few years ago and asked Double-S if they could make another set for him. They told him they that they no longer had the jigs to produce them but said they could provide the bent pipes for him to assemble and weld himself. Terry subsequently got three sets of pipes and made some manifolds for himself, Ian Stainburn and Trevor Shortt. Terry said the pipes were fairly cheap so if you are adept at stainless welding, or know someone who is, it could be a good option. Remember that these are the long-branch manifolds developed by Don Pither and therefore don't suffer from collector damage in the same way as short-branch manifolds do.

This was a while ago but a call to Double-S might be productive. :)

Update , QRG can’t do them as they need templates but they buy from Double S exhausts in Exeter . Called Double S and they say it’s probably cheaper to buy from Graham Walkers as they won’t undercut there agents . But if I bought via a trade they could do them 4 weeks lead time but Xmas might slow things down a bit . Confirmed twice that I needed V6 Coupe manifolds and assured me no problem 4 weeks wait . Cost about £400 ish plus vat .
So rung Graham at Graham Walkers yes he buys from Double S BUT they can’t make them as they have no jig .

So here’s the offer . Graham at Graham Walkers said if anybody can leave a running V6 Coupe at Double S for a couple of days they will build a pair of manifolds and jig them for a production run and even better Graham Walker will pay for them .

So you would get a pair of manifolds at no charge , Double S get a set of jigs , and Graham Walker gets to stock and sell manifolds again , and I can buy a pair .Everybody wins

Does it have to be running? I could be persuaded to take one down on a trailer and leave it there for as long as required.

Probably not , just needs to be rolling and engine , gearbox and everything relevant to fitting manifolds in place .

Jim , speak to Graham

If someone takes a car for the samples/jigs to be taken from please make certain the engine and gearbox mounts are either New OR in great condition.

There has been a few issues with 2.8 tubular manifolds from Double S, and after speaking to them it would appear they took some measurements from an Old car and the passenger side manifolds were bent slightly too tightly and now foul on the chassis and bodywork in the engine bay.

I spent a few hours trying to get a pair to fit a GTC a few years ago, and when I gave up on them the cars owner rang Graham, whom he had bought them from, and another side was sent which was the same as the first one, I had to set to and tweek the passenger side as the car was booked on a ferry to France.

Just my Tuppence worth, not knocking them, or GW.

I think Andy AJL has a similar problem with a 2.9 set - not sure if it was the mounts or the builder?

I’ll try and ring Graham this week.
