Hello all,

I had a quick question for anyone that might be in the know. Can you guys (& girls) tell me if the large resonator on the OEM B-Pipe is made of stainless steel? I know the piping itself is, but what about the resonator.

I ask because I grabbed a used JDM b-pipe from H-Motors and had to sand some rust spots off the top. At the time I just assumed it was stainless, and went ahead and installed it. Of course now that it's mounted under the car, I'm second guessing myself. Does anyone know for sure? If not, what is a good way to check. I remember something about "magnets not sticking" as a good identifier of stainless steel.

The magnet says it is not.

It depends on the stainless steel. Walk around with a magnet inside of an appliance store or a commercial kitchen and you'll find a lot of "stainless" that is still magnetic.

From our friend Google:

" A basic stainless steel has a 'ferritic' structure and is magnetic. ... However, the most common stainless steels are 'austenitic' - these have a higher chromium content and nickel is also added. It is the nickel which modifies the physical structure of the steel and makes it non-magnetic."

Interesting. The piping itself did not attract the magnet. I will probably just check on it in another month, and paint it if it looks rusty.
