As a new buyer looking for an "automotive" product I expected a product that would consider the noise levels, but as a result of using this product, I found that the "Quiet Flow" muffler is far from quiet.It was disappointing to spend money on a muffler that doesn't fulfill its purpose, and instead made my car louder. The only positive thing is that it has a nice stainless steel finish, but that`s hardly worth the price..
