My favorite exhaust was on my DartSport, it was a 3.5" X-pipe with Magnaflow race mufflers and turnouts to the side of the car. Fairly quiet on the street and sounded like high RPM when I hammered it. This car ended up going 9.80's through the exhaust footbraking and the exhaust didn't slow the car down one bit compared to open headers, it actually helped since it was a hundredth quicker and the system easily weighed 75 pounds.
