Comments about Walker Quiet-Flow SS Muffler Assembly:

This is NOT a Stainless Steel Muffler, only the End Tips are stainless steel. This muffler was delivered damaged. I had to return it to a store to have them reorder and pick up the next day. They were very helpful at the store. This muffler (even with a $50 discount) should have been a Stainless Steel Muffler, not just the 4" End Tips. The price online also went up over $308 the day the muffler was delivered. OEM products always cost more, but this muffler is way overpriced because the 4" SS welded End Tips.
