After I put it to the TEST, i was blown away by how well the muffler worked. It gave my car a whole new sporty look and growled like a beast upon acceleration while remaining silent during cruising .The installation took only 30 minutes, making it an easy upgrade for any car enthusiast. The only con is that its a bit pricier than some competitors, but the quality definitely justifies the cost. Overall, a great investment for any performance car..
