flowmaster stainless system stainless steel or ?

i ordered the flowmaster 817116 american thunder for my 92 gt and took it to a shop to have it ceramic coated. They took a magnet tool to it and said it wasn't stainless since the magnet stuck to it. If there is stainless steel it's a very low grade. I wasn't happy since I paid good money for stainless and it isn't or barely. This is the first inquiry I've made about it and would like to know what is the system made of. They weren't trying to sell me something more expensive just showing me the difference in your system and another pipe that was stainless that didn't attract the magnet. thanks

i did some research and basically it is a low grade of stainless steel and there is some magnetism to it. Does make me question the shop tho.

Dont ever go back lol, any 8th grader will tell you steel is magnetic and aluminum is not. Even low grade steel will out last any aluminum junk pipes. Use the vht ceramic paint to help prevent any rust

i went ahead and left it that day and they did a really good job. Hate to put on car now. p/u today and he said it's like a low grade but still a good system, kind of a buying generic something. Magnaflow is supposed to be all stainless but more $$, that's why i went with flow, get what you pay for. that system won't rust now, it's all coated.

There are several different types of stainless steels. The two main types are austenitic and ferritic, each of which exhibits a different atomic arrangement. Due to this difference, ferritic stainless steels are generally magnetic while austenitic stainless steels usually are not. A ferritic stainless steel owes its magnetism to two factors: its high concentration of iron and its fundamental structure.

that hurt! I think he used the less magnetic steel as an example, it was some kind of turbo tube with a heat wrap of some sort that made of steel I believe. Either way I'm covered and know to get magnaflow next time.

Your Flowmaster system is made of 409 stainless steel and is backed by a lifetime limited warranty against defects in materials and workmanship. You can rest assured that you did not purchase a generic system in any way. Don't be fooled by competitors pictures of shiny systems that simply state that they are "stainless steel". Not only did you purchase the best sounding system for your car, it will be the last system that you ever have to purchase for your vehicle.

thanks Matt. I was going by what the ceramic coating shop said. The last system I bought was a flow master and it was back in 1994 and lasted up till this point. When I took the old system down there was loose pieces of metal in the passenger muffler. I'm guess whatever is used to bounce the sound around rusted out or whatnot from condensation over the years. it wasn't stainless steel. I'll cutr it open sometine and see what is rattling around in there, not sure when it happened.
