The delivery of my parts was spectacular. Very efficient, uncomplicated and timely. The delivery cost was reasonable at $50. The mechanics at my garage had no complaint regarding installation save for a clamp that was required and surfacing a piece of pipe from my old exhaust to fit the new system efficiently. I don't know what that was. However, the exhaust is louder than I had anticipated. There is also a back exhaust vibration when the car is gearing down. Also when rapidly accelerating. It's kind of similar to the way the old MGs used to sound. The noise from the exhaust it's obvious in the cabin area of the car. The noise is loud enough to be obvious yet I wouldn't describe it as annoying. I would expect and recognize that the exhaust sound of this car is supposed to be quieter than it is with your product. I am not disappointed with your companies service and I am hopeful that the product will not underperform regarding longevity. I suppose that aftermarket materials are not necessarily to specs of original parts. I certainly have not paid dealership prices for your components. Hence I shouldn't necessarily expect comparable performance. I do not regret my transaction with you and your company. I should become accustomed to the peculiarity of my exhaust. I pray that it doesn't become worse and annoying or unbearable very soon.
