Should the RMB stainless steel exhaust last a lifetime? I have one that rusted after 12 Yrs. I thought these would never rust.

I would think they would last a long time, but perhaps if used with an overabundance of road salt, they might not.

Perhaps there is more than one manufacturer and varying selections of metal as well.

Lifetime I doubt, and maybe 12 years is about right. I think it is more about miles and the normal environment it has lived in during that time though. I have had an RMB on my S4 since they came out and it is NOT a SS one... My '92 GTS also has a regular RMB on it that is at least 10 years old and neither of them are showing any signs of rust that I can see. These cars have each gone about 30k miles (guessing on the GTS) with the RMB's in place just so you can get a feel for how much driving they have on them.

There are quite a few different grades of stainless steel, with widely varying degrees of corrosion resistance, and corresponding differences in cost.

I deal with salt issues all the time. I have found that stainless is exactly what it says. It STAINS LESS!!!!!!!

I supposed everyone has a good point. I'm very dissatisfied that these didn’t last. I've installed stainless muffler and pipes on my other cars and none of them have rusted yet. Interesting though is my original mid section OEM resonators and cats out lasted these RMB. Any suggestions for replacement?

What about taking it to a decent exhaust shop (not a Meineke), and have them replicate it with some higher quality tubing?
