944 turbo - rear exhaust section replacement advice/experience please

[Paul 290T]

Hi,

The 8 inch tailpipe section fell of my exhaust last weekend. No problem i thought the last rear section from Porsche (in 2000) only cost about £200. Shocked to see the cost is now around £900 (Design911 for OEM).

So my thinking is that a stainless steel rear section (£420 Hayward and Scott, £189 MIJ Exhaust) which will outlast the standard galvanised section is a more sensible way to go. I plan to keep my car for a long, long time.

Any experience you have would be gratefully received. i am particularly interested in:

a) keeping the sound as quiet as standard.
b) appearance as standard
c) which after market systems you might have married to the OEM mid section (which is stainless steel)

Thanks

Paul

If the rear box is till OK apart from the tailpipe, why not weld a suitable new tailpipe section onto it, as you may still have lots of life left in the rear box? ... on reading your post again, though, have you lost the whole box?

The tailpipe dropping off is a common transaxle occurrence, unfortunately.
Many years ago, I remember mine dropping off my 924 Turbo. I stopped and walked back in the pouring rain hoping to retrieve it, only to find another vehicle had driven over it, completely flattening it [&:]... not much use like that

I had thought about getting just a new tailpipe welded on. And I haven't written that off, but welding to galvanised steel means first grinding off the galv to expose the mild steel, as galv can't be welded to. I have my doubts that the resulting exposed mild on the steel back box will last long.

Stainless Dansk were the usual option, I can't see a turbo version for sale now though. I just happen to have a VGC one in the shed.

From what I can gather stainless Dansk exhausts for turbos are no longer for sale. Is yours for sale?

I got an OEM back box for about £200 about 8 years ago. My tailpipe fell off about 3 years ago. I went to a stainless exhaust place and had a stainless tailpipe welded on which looks very OEM like. The note did change a little bit but I like the noise. Cost me £60. Still going strong today.

That's good information Stuart, obviously the exposed mild steel does not corrode very quickly, 3 years and counting for £60 is very cost effective!

I wasn't planning to sell it, but if you want to make me an offer and pick it up from Cambridgeshire we'll see.

I can fully understand you not wanting to parcel up and arrange collection for something as large as the exhaust. I live in the NE, so collection is a bridge too far for me. Thanks anyway, but I will respectfully pass.

No problem.

It may have been but for a while now it's been a mild steel tip if bought from OPC. Seems a bit mental really but they must have their reasons.

I had a full 3” system made by AAS at Newburn for £550 a few years back, sounds like this:

Alternatively, Exhaust Doctor at Shiremoor will weld a new tip on for you and have a selection to choose from too.

Ask people that were around in the day what the twin pipe exhaust on WUF sounded like [].

Thanks for your help, this morning I read your thread from 2015 when you had this exhaust fitted. My car runs 290bhp on the standard turbo and the car in general looks standard, something i intend to keep. The manifold, downpipes and mid section are all okay. As far as i know the centre section OEM exhaust is stainless anyway. I am going to ask AAS if they can make me just the rear section. However at £550 if they say not possible I'd be happy to go for a full system.

With me wanting to keep things standard looking, and now sounding, how would you compare the AAS system to OEM when cruising?

AAS make the race exhausts for many of the 924 Championship cars. Having a rear section made by a company like this is they can apply a silencer with a noise to your taste. One mans noise is another mans music.

do they still do exhaust pipes in Inches?

thought it would be in mm now, 75mm ID
A friend had a cat back system made by Pipecraft in Basildon for his 968, bit louder, bit lower growl, and seemed quite ok on a cruise, £550 all in and fitted

Tony you are quite right, i stand corrected. I put a magnet on my OEM rear section of exhaust. the tubing, except the tailpipe, and rear silencer case were none magnetic, meaning 304L, one of the better grades of stainless used on exhausts. The external brackets and supports welded to the exhaust are mild steel. I think something inside of the exhaust must be mild steel too, as there is a magnetic attraction on the silencer end caps.

 

[Paul 290T]

Could someone do me a big favour and measure the vertical and horizontal diameters of their OEM tail pipe chrome finisher?

I will get a new section welded to my otherwise good condition rear section of exhaust. i want to keep it all looking standard.

Mine isn't OEM so will leave it to someone's whose is.
