I have a muffler off of a 2001 RS.
I bought the car used and this muffler was put back on, due to the previous owner having an aftermarket exhaust.
I recently had a custom midpipe welded to a WRX axleback, and I am planning on staying with that until I get another catback.
It's been in the garage for about two month so I'll go out and clean it up and check for any rust. From what I remember it was in great condition. Now the catch, when I had my WRX muffler installed the shop took off the front exhaust hanger of the RS axleback and used it to make the WRX muffler fit. So basically I have a good muffler with just the two rear hangers and about 30k also on it. LMK.
