I hope after DFs instructions these photos actually appear!!

In a previous post I said I would try to get some photos of my exhaust which I am sure is past its sell by date.
It is very rusty and appears to have no 'flex' in it so I fear it may go at a critical time!!
The ID is around 2"
Would I be able to make one up using straight rubber onto the flanges with one 90 degree elbow in the middle or what do the experts recommend. Thanks for all the tips so far, there do seem ( as advised) to be some likely bits at ASAP)
Regards Peter
 
It looks as though it is a dry exhaust ie no water cooling. If thats the case you cant use any rubber bits because they will burn.
 
Yes you are right Vic I tried to correct my stupidity before anyone noticed. Is the best bet just to take the lot off and get a new one made, perhaps using the existing flanges. How essentiall is it to get some flexi pipe into it?
Cheers

Don't forget that for a period (Not sure if it's 1 hour or 2) you can edit you original post.

However the exhaust. A flexible section would be nice but whether it needs it rather depends on how flexibly the engine is mounted, how long the pipe run is and how that is supported. I think you said it originally had a flexible section if that's the case then yes include a flexible section. I've no idea what you would use to make it though.

I wonder if an decent independent car exhaust place could come up with something.
Not somewhere like Quick Fit obviously
 
Wander down to your local truck exhaust place. Hopefully the steel pipe from the flange is a standard size and you should be able to buy SS clamps and SS flex pipe to suit. Minimum length of about 300mm but in your case may as well have a piece to take in the whole curve. Its not that expensive and is common on trucks. It does handle some movement but is mostly there to allow for expansion in a dry exhaust. Lagging it will aid in reducing noise and heat as well.

In the NW (Where Pcatterall is) try CES. I think they might be wholesale, so he might have to do a bit of sweet-talking, but money is money at the end of the day.

Flexible connections are certainly available, either spiral wound or convoluted - but he'll need to know the system diameter.

A google search produces some interesting results

The hoses and fitting on This site look particularly interesting. In Lancs too.

Artificial Intelligence is no match for Natural Stupidity
 
There is a truck factors on the deeside industrial estate, I can't
remember the name off hand, but they were always really good
with me, even for car brakes and rads. They specialise in truck
brakes. The unit is in the next one up from Witters if you are approaching
from England.

I will try to hunt out an old invoice later, I should have something in the car file.

Otherwise, there is dieselcraft in Widnes, they are always helpful too.

Or, take an afternoon off and have a trip down corporation road in Birkenhead, it is
the scrap capital of Europe down there, proper yards with proper blokes, none of
these southern nancy off the shelf outfits, you can spend an hour looking for
something to fit.

Ahhh, be aware, neptune is the most expensive.

[/ QUOTE ] Not entirely Peters fault. The photos were individually within Dans size guidelines.
The stupid forum software stitched them together. I would not have expected it to
do that although I would have spotted it in Preview and fixed it. This was Peter's
first go at posting photos so he would not have known what was happening.

Now if you really wanted to be helpful you could have shown him how to post them
as clickable thumbnails /forums/images/graemlins/grin.gif

Thanks for all the response on this one. The marine store stuff looked good but only up to 1.5" Will be grateful for more info on suppliers fabricators around Widnes. Yes, those clickable thumbnails looked good I will have to do the advanced course!!

Try a Google for custom exhaust manufacturers.
These are the guys who make up stainless boxes for the boy racers. They tend to have a variety of sizes in flexible stainless steel tube on the shelf. I would also suggest lagging the entire length as that cooling hose is a bit close.
 
I have just replaced my DRY exhaust with wet one glad I diddisintergrated when removing it, it was made off two pipes one inside the other and the water passing in the outside jacket, involved replacing everything from manifold back but now works realy well, good news is original one weighed over 40KGs and 18kg was copper pipe got £54 from scrap man !!!

Looks like you problem is getting the initial drop if you go for a wet exhaust.
 
My only experience of flexible metal exhaust pipe was on an old Riley car, and on that basis, I can't say I'd recommend it. It's OK for making installation easy but after a time it went rigid and no longer coped with engine movement, failure soon followed. Perhaps newer types are better.
 
Peter, I'm not sure if the original exhaust system had lagging on it, but when you instal the new exhaust system I would suggest that you fit a good quality heat resistant lagging.
