Stainless Steel exhausts

[DEP]

Been thinking about changing the exhaust on the cossie escort, Went along to Long life in Basingstoke yesterday and he quoted me £349 for a 3ins system single box and a rolled tail pipe, To me that does nt seem too bad, What do you think, and has anybody got any other recommendations for an exhaust system, preferably in the south.

Thank you.

you have a cossie? what one?

Sounds reasonable to me, it's a little more than I paid for my long life system (about £50 more I think) but mine is only 2 1/4", they look nice and sound good, plus the rolled tail pipe is quite a nice finish. I've heard good & bad things from people about longlife so guess ultimately it's down to the skill of the fitters at the centre you take it too.

Thanks Colin Sorry my mistake, i forgot to add escort to the end of that, now edited

 

Ok thanks Scott, the guy i spoke to seem to know his stuff

Ian,

 

Richard had his manifold made at Power Speed in Ashford in Kent, they do stainless systems too. Mention that Richard with the Anglia said to call him, I am sure he will do you a special deal. I am getting mine done there (when its all back together again)

I know of 2 exhaust manufacturers who I personally know and would reccomend as I know what they use and what they put inside the boxes, funnily enough they are both in the North.

Tube Torq in Macclesfield and

Tony Law Exhausts in Leeds

 

Make sure they are using good quality UK sourced St St and its at least 1.5mm thick, dont bother if its any less....even if its 1.2mm. Thats too thin and the st st reverberates and it gives it a boom like sounding quality.

Cheers for the advise Jon

That's who did my exhaust on the van. 3 inch tube. Two boxes. That was £300 plus vat.

In st st?

 

Hayward and Scott in the south! They made mine, it fell appart a lot, but they always fixed it for free I think st st is not as strong as Mild so they have to be "hung" carefully and no too rigidly.

 

The best weldering tecnique is to purge the inside of the pipe with argon (or whatever) at the same time, which protects from the inside aswell as the gas that comes from the torch. This improves the weld quality and strength, particually on stainless.

Powerspeed gets my vote You can tell them I sent you but you won't get any discount

I had my Capri and Golf done at Longlife in Wallington. No probs at all

 

Colin Ashton is only round the corner, you could sit and talk bo**ox with him while they're doing it

Stainless Steel , fooooking horrible shite stuff . Mild steel is the daddy

Oh yea Gaz...............Have you got first hand experience of them then

Get yourself down to powerspeed in ashford mate then you can drop your old exhaust round to me as i still need one for mine i'll swap it for a cuppa

[BIG G]

Stainless is to heavy mate and work hardens and fractures to quickly and will make your motor sound to rice rocket like..... thats my opinion

No problem mate.

Ok, who would you reccomend then mate?

[Guest MK1gaz]

I recommend not using stainless

Very good but.... he said who, not what!

Make your own its easy

 

you must be able to buy a cossy 3" front pipe section then get some pipe from camberly auto factors a rear box from flea bay hey presto. or contact janspeed their only in salisbury.

Thanks G , but i dont have the tools, knowledge or garage /workshop to make my own

Ok the case stainless over Mild steel.

 

Stainless for me for a number or reasons. Principally because I don't want to have to replace it in a few years time, but also because they're offered with a life time guarantee that you'll not get with any MS system. Plus I don't like a rusty looking tailpipe sticking out the back.

 

Now as regards the weight and brittleness issues that have been raised, yes stainless is slightly heavier, for example: -

 

Stainless (dependent on grade) weighs approximately 7900kg per metre cubed

 

Mild /carbon steel weighs approximately 7850 per metre cubed

 

So if your exhaust is the size of a small ocean liner it will weigh approximately 50kg more for the same thickness of metal. On a car however the difference will be negligible and in reality given the following facts is even less than you might expect: -

 

Stainless tensile strength (grade dependent) 515 -827 Mpa

Mild steel tensile strength (grade dependent) 276 -1882 Mpa

 

As both system (be they stainless or MS) will likely be made from grades from the cheaper end of the market, the facts show that Stainless is signifcantly stronger. Therefore the same tensile strength is achieved from a thinner tube ergo less weight for the same strength. i.e. a Mild steel system will need to be 3mm thick to achieve a strength that could be achieved with 2mm stainless.

 

Mild systems also need extra thickness to prolong their life against the effects of corrosion, stainless ones do not need this.

 

Now as regards brittleness / fracture if people have been suffering from this it's likely that the grade of stainless used in their system has far too high a carbon content. In a car exhaust application stainless should not suffer any problems with fracturing a 300 series grade of stainless should have an adequately high modulus of elasticity for there to be no issues. I have a stainless exhaust in a project I'm involved with, it endures far higher temperatures than a car exhaust and undergoes significantly higher shock loads and stresses, no problems to date.

 

 

Edit: oh and mine sounds ok, at least it does from the inside. I've never had anyone drive past me so I could listen to it from the outside

Hayward and scott quoted me £400 for a system,downpipe back. Or £650 with a downpipe. I opted for 2 meters of 3" stainless pipe and a cossie back box for £120 complete and my mate welded it together for me.
