Purchased from Advance Auto Parts 3rd ago years, now the exhaust is falling off. For the price I don't think it's bad. But the original muffler lasted 16 years in upstate New York with no problems. Pros: Inexpensive. Matches well with other Walker exhaust products on a 2002 Toyota Corolla. Cons: rust. Be sure to cover with anti-corrosion paint before installation. Spend a lot of time preparing the surface. I wish I could.
