I'm not bothered with rust on the exhaust, I'd expect it almost.

If it really bothers you, you could always rplace witha stainles item, that will come with a lifetime warranty

I agree with Rich on this one. I must be missing something on this thread. All cars, whether they are 'German' or not, suffer from surface rust on general chassis components. Exhaust brackets, suspension arms etc. etc. It's perfectly normal, unless, as already pointed out, they are stainless steel or painted.  Gone - TD4 XS Auto, Sumatra Black, Mud flaps and side strips, clear indicators, private plate, privacy glass

Land Rover website claims that ALL exhausts are stainless steel as standard? EY's car and mine are MY11 cars,

Mona Geeza, don't know about yours
Land Rovers site says different, all genuine exhausts are Stainless Steel, hence the question of 'When did it change' (if it ever did)

They arn't stainless steel as per the 'performance car/hand made' path but they do contain 'some' stainless steel in the manufacturing process. Ours is a March '08 car with the original exhaust on and the exhaust tubing is brown horrible and rusty - Best get the autoglym out for the meet (The rear silencer box is mint courtesy of some black stove enamel paint )

So the tweaking and cleaning has started for the 14th,must admit Mr Struts tip re the silencer box is did mine and have had the approval of Mr Strut

From what I have been able to find out from a metallurgist friend, the more upmarket car manufacturers use ' lifetime of the car' stainless steel.

This is usually the cheaper '409 series' with 11% chromium added but no nickel, for corrosion resistance and anti flaking. It will discolour and give the appearance of rust but will not metal flake for a great many years.

Performance exhausts use '304' with a higher chromium content with the addition of 'nickel' for anti corrosion, '304' will allow the shine to stay except where it will 'blue' with heat near the manifold.

Alluminised is a coating on 'mild steel' and while it lasts longer than mild steel, it falls below '409' quality.

he is probably getting mixed up with the cat/dpf wich are stainless the rest of the exhaust is alu coated steel, rainy-city

So Land Rovers quote

Quote:

Material Strength - Stainless steel is used to give the entire exhaust system a robust and durable structure, able to withstand exhaust gas temperatures in excess of 700ºC.

from the link I posted earlier is a complete lie Do you think they would run the risk of stating one thing when its another

It is Stainless Steel, f d if I know what f g grade, but it is Stainless Steel not Alluminised mild steel.

Mine is definatly stained stainless steel. I know that because its a brown rusty looking colour. However very glad to hear that it will last the life of the car, cos have no plans of selling yet  2007 Freelander 2 HSE TD4 Manual with Premium Pack & Moonroof.
Stornoway Grey with Ebony Black Pleather, Clear Indicators, Body Side Mouldings etc.

.... and before someone points it out that a magnet is attracted to the metal so it can't be Stainless Steel, that is because it is low grade 'Ferritic Stainless Steel' so has a fair amount of carbon in it.

Nevertheless as Andy pointed out, it is dirty, stained and brown, but is SS
