I don't know if they do the Legacy muff in stainless. For what it's worth, for anyone who's interested in Stromung stainless mufflers, I've examined the stainless muffler for the Impreza in person, and only the outer case is stainless. The inner material is the same as the non-stainless i.e. mild steel. So I don't think longevity will be any better with the stainless exhaust, but if it's looks you want, I'll email Stromung and see if they do the Legacy muffler in stainless.
