The end result is a highly optimized upgrade for your Porsche for both street and track use! Many enthusiasts modify multiple portions of the exhaust system in pursuit of power and tone which can increase the volume and cabin presence beyond their preference. The primary benefit of the resonated version of our over axle pipes is gaining the performance increase of removing OPF filters without increasing volume to a great degree, whereas the \u003ca href=\"https:\/\/eurocustomspr.com\/products\/porsche-718-gt4-cayman-competition-over-axle-pipes\"\u003eCompetition Over Axle Pipes\u003c\/a\u003e offer bolder tone and volume.
