I have a Flowmaster 40 Series muffler (central in and out) with a welded stainless steel tip for sale (bought if for $100 on ebay). I am looking to get around $50 plus shipping for it. The muffler was on my car for around 1.5 to 2 years. This is a relatively quiet exhaust but it is still a bit loud for my taste. However, it sounds perfect. I will try to post a sound clip if I can find one. There is some rust as evident in the pictures but it just seems to be a surface layer. I scraped some of it off and the underlying medal seems to be alright with no rust throughs.
