Title: Good fit, So-So Quality
Review: I purchased this muffler through Amazon in July 2010 as a direct-fit replacement for my 4Runner. It bolted on very easily and sounded just like the original factory muffler that had rusted out after fourteen years. The problem started when I went to replace the downflow O2 sensor last week. The studs that hold the sensor to the pipe had completely rusted to the point where I could crumble the threads with my fingers. The studs are now completely useless; the only thing holding the sensor to the pipe is the rusted mass.When I called Walker to inquire about the warranty they directed me to Amazon, saying any replacement would be handled through them. A little strange but we'll see how that goes.
Is the review positive or negative?
