Based on my observations, this muffler does not deliver on its advertised promises .Its performance is subpar compared to other affordable options in the market. While it claims to be "quiet flow," it produces a noticeable increase in noise levels inside the car. The stainless steel build quality is commendable, but it does not justify the exorbitant price tag. Automotive enthusiasts will do well to steer clear of this overhyped product..
