Bought and installed these original 40 series mufflers on my 2001 monte carlo. It makes a great roaring sound that's controlled as per the throttle response. I can take off with easy acceleration and it makes a noticeable sound (roar) I slam the pedal to the metal and it gets much louder which is exactly the type of sound how and when I wanted. No interior drone. So this was done on my stock everything v6 3.8L engine. Now i can imagine the sound from these mufflers onna v8

sound awesome
