Certified Magnaflow muffler! Great quality!
Was skeptical at first about ordering this muffler wondering if it was going to be a legit magnaflow product. Came on time & was definitely %100 magnaflow quality. Just installed it today & was exactly what I was looking for 👍 nice low gentle grumble on idle
