As it was of interest and debate, here's a bit about Magnetic Stainless Steel...
[QUOTE]There are two primary categories of stainless steel tubing used in automotive exhaust systems: 300 series and 400 series. 400 series stainless is commonly used by Bob's Muffler for exhaust because it handles heat cycling better than the 300 series. 300 series stainless becomes brittle after constant heating and cooling (which is exactly what an exhaust system does) especially in areas that incorporate welds. The issue of heat cycling is of great importance, especially in a heavy-duty application that will endure greater levels of heat than other automotive applications. Not only is 300 series stainless a poorer choice for exhaust systems, it is also more expensive and would unnecessarily increase the price of an exhaust system. 400 series stainless is not as pretty as 300 series and will have a brownish hue to it, due to the fact that it has a higher carbon content than 300 series. This means the 300 series stainless will polish up better for appearance. The carbon content in 400 series also makes it magnetic, unlike 300 series, which is a simple test to determine which series you

True but....
Most aftermarket systems are 300 series and will outlast the life of the car! If you imagine the manifold and system on ours, and many other turbo cars to be a mild steel, and tend to last forever anyway - the benefits of going to something with better thermal fatigue properties are pretty much a waste of money.
Thermal cycling is more an issue when you are dealing with very high / low temperatures.
400's are martensitic, but ive never dealt with them so cant really comment...
