kevin2 What did you say? No I have not blown out the mufflers yet. How you drive is how quiet or loud you want the car to be. The down side to the exhaust system is a power loss. Between 20-50 hp and almost the same on torque. They have noise levels at some autocrosses and my 15 year system passes. I have also a race setup too for tracks without limits of noise. I believe if you check with some of the older owners you will find the same thing. If you should go for a long road trip an ear plug for the outside ear wouldn't hurt. I do get the ringing ear after a race run without a ear plugs and helmet.
