Based on my observations this muffler failed to live up to its claim of being "Quiet Flow." The noise reduction was barely noticeable, and it actually hindered my automotive performance.The only pro was its stainless steel build, but that doesn't make up for its lack of effectiveness. I wouldn't recommend this product to anyone looking for a high-functioning exhaust system..
Pros
Reduces noise pollution and provides a quieter ride
NOT AS ADVANTAGE! No walking stamp! NO STAINLESS STEEL! I received a very old dented aluminized steel Maremont 230699 which is not a direct replacement for the Walker 40070.
