Review on Walker 21284 Quiet Flow Stainless Muffler by Zachary Greene

I bought it in 5/2013. Although a bit pricey, it looks and works well. The selling point for me was 100% rustproof. When I dropped the exhaust system to fix the cat I noticed that the top of the muffler was starting to rust internally and the side was chipped! Hm? Doesn't look like stainless steel. Well 3 years is a good run I guess. (April 9, 2016)
