3" Downpipe has arrived - warning Shiny!!

[GPF]

As the title says really.....[]

Looks like excellent quality from Hayward and Scott. Hopefully it will bolt up nicely, although I need to get some studs fitted, or more likely add some captive bolts to the bottom flange - I should have specified that in the first place!

The 3" exhaust has also arrived, but I still need the big lad's turbo to bolt to the other end.....coming soon!

Edit : Bugger, how do you display photos then? [8|]

Ooooh very shiny [8D] Did you say they were charging around £150 for that? If they are it sounds very good value, as long as it fits okay []

I took the liberty of editing your post to include the pictures instream ( you have to surround the URL with a

Interesting, thanks.
Would you mind posting some pics of the exhaust too?

Looks brilliant, may well be in the market for just such a thing presently..

Thanks Paul!

Yes, £150 plus Vat & delivery. Mind you that was as the original estimate - I don't know if they will do any more for the same price now they know what's involved.

Thom - I'll post the exhaust (front section) up next week - it's still at work at the moment.

Here is the rear though.

Booootiful rear section there. Pls take a photo of your car once the back box is fitted. []

Cheers - that's been fitted for a few years. It's only now that I'm adding the 3" downpipe and the matching front section to it.

If you follow the link in my signature (the blue "88 Turbo S 330") there are a couple of pics from the back in the "951" album, although none that really show the tail pipes properly. They are 3.25" diameter - I'll see if I have any photos from the n/s/r quarter for you.

I have been considering new exhaust for ages, is the 3" downpipe going to be for sale as normal or special order only. Also is the H&S exhaust 3" all the way? Cheers

I don't know what they will do about the 3" downpipe - as far as I am aware, mine is the only one they have made. I sent them my original to use as a pattern and I presume they made a jig from it so I would imagine that they will happily make one. But everything is special order in the sense that they have no stock so each order is hand made individually - which could take 6 weeks.

The exhaust is 3" front section with no silencer, reducing to 2.5" for the rear for applications up to 400bhp. They don't recommend going to 3" all the way unless you are at 400+ as they say your mid range will suffer a little without any top end gain bellow this. (Below this they told me you don't need that volume in the rear section, and as the gasses have cooled and contracted by then keeping to 2.5" at the back helps keep the gas speed up to aid extraction/flow)

I think really that you need to do the downpipe and the front section together - the 'standard' front section reduces down to match the original downpipe flange and use the factory sealing ring. Do them together and you get the full 3" join straight through which must be quite significant at that point in the system.

You can spec your own style of tailpipes for the rear, and everything is guaranteed for 25 yrs I think!

I have no connection with them by the way![&:]

Is a downpipe and a turbo discharge pipe the same thing?

Anyone heard of Longlife exhausts?

 

[Fat Albert]

I believe the downpipe and wastegate discharge pipe sit alongside each other. I replaced my discharge pipe earlier this year, I found a S/H one on eBay for £75,they are £280 new!

The downpipe takes the used exhaust gasses away from the turbo - i.e. it is the first part of the exhaust after the turbo. Also sometimes called the turbo elbow, and I guess the turbo discharge pipe sounds right.

The wastegate discharge pipe - usually/also called the dump pipe I believe - is part of the system to divert exhaust gases away from the turbo. i.e. before they even get to it, and it is not alongside the downpipe. It allows the exhaust a path to get straight into the centre section of the exhaust under the car.

 

[Diver944]

Here's a useful underside picture of a Turbo which shows the jacking points and I have annotated the exhaust components so we know what we are all talking about. I expect to see a similar picture of Grahams when he has fitted all the new bits []

Hi Guys

Now we have the jig we can offer the Turbo Elbow to other customers for a production price of £195 excluding VAT (The price of £150 was a reduced price for letting us have the pattern to be able to make the jig ). I only think it will be beneficially when bought with the down pipe , unless you have one all ready end then would recommend getting it modified to a genuine 3" pipe at the top other wise you would still have the same restriction as standard and wouldn't gain from having the Turbo elbow fitted.

Hope that makes sense [&:]

I think it may be possible to gut a standard elbow, if I find a cheap one I'll have a go though I don't think that Porsche double skinned it to restrict performance, more likely to keep some heat away from the plastic AOS.

Very Shiny!!! [8D]

Which is why I will be covering all that shinyness up with exhaust wrap [8|]

Forgot about this, here you go.

and with the downpipe fitted.....

There are a couple more in the "Exhaust" album on my photobucket site (link in sig below)

I test fitted the full system using the SFR turbo yesterday as the new one should be here this week and I wanted to know that the new exhaust parts did actually fit before adding another variable! Just getting the existing turbo back on and in the same place was hard enough [], but a bit of grinding here and there made it easier to get the new bigger exhaust up to the downpipe. I also cut the bracket off the downpipe - that just gets in the way![&:]

All back apart now, waiting.....

I also keep looking at the manifolds - anyone know just how difficult a job it is to get them off?? (apart from rusted/siezed fastenings)

 

[TTM]

Nice, thanks.
What sort of budget did the complete exhaust run you?

 

[GPF]

I think the front and rear are now £575 the pair and the downpipe is £195. Both plus VAT and delivery.

 

[marcoturbo]

very tempting...

Can the dual tailgate of the rear section be changed to an oval factory look tailgate ?
