I have a 92 fwd legacy with the original exhaust system , I cant believe its lasted so long. Last year at inspection my guy replaced a gasket but thats all its ever had done. Now I notice about one square inch of rust bubbling on the muffler and its up for inspection in 2 months.It is not a hole , nor is it leaking but I dont know if they will fail it for the rust or if the rust will be a hole very soon. I would be appreciative if anyone has recommendations on which way to go if I do the muffler myself. Subaru or a local parts store? thank you.

Or you could try removing the rust first, and protecting the area with rust inhibiting (high temp) paint to make the stock muffler last a bit longer (like until after the inspection) so you have a bit more time to select a good one. . .

I can personally attest that getting an exhaust off, say a BD/BG Legacy (95-99), might be worthwhile. Just stick with the right body style, sedan or wagon. I have a 98 Legacy GT exhaust (midpipe and muffler) that I bolted up to my 91 Legacy sedan with no modifications whatsoever.

I was going to doctor the rust spot and ask my guy if that would be ok.

 

How can I tell what exhausts from later years would work on my car? Is it thru the body type or engine? I have no clue. Thank you
