Default Re: Magnaflow Exhaust from Needswings

Most of the hardware on my sailboat is 316 and 304 stainless and after pounding through waves for weeks at a time it absolutely does rusts.
In the auto trade most exhaust systems are manufactured using 409 stainless which is even less resistant to corrosion.
