Review on Gibson 319000 Single Replacement Muffler by Shahed Nyuon

The Gibson 319000 single replacement muffler is a great investment for anyone looking to improve their performance car's exhaust system. Based on our own experience, we have noticed improved horsepower and a deeper, more aggressive sound. The installation process was straightforward and the muffler looks great UNDER the car .However, the only con is that it is slightly louder than the stock muffler, but that is to be expected with any performance upgrade. Overall, highly recommend!
