Yes, you can hear the exhaust from inside the car, especially around 2500-3000 rpm. I do not know how to post sound clips or I would share. Not as loud as I was expecting from inside but this could be due to the well insulated car. Ron at Performing Imports is Very knowledgeable and straight forward...highly recommend. I was on the fence about the color, originally decided black but finally went with silver because my car is a dark color ( carbon black). Honestly I wanted the tips to be seen! If I had a white car... Definitely black. Eventually I will install stage 3 because it is compatible with the free flow exhaust..... Waiting on the 20% off on software! If you decide to go Dinan I doubt that you will regret it
