VIBRATION / NOISE

Supercharged Group: Forum Members Last Active: Yesterday Posts: 3.7K, Visits: 32.4K	My Car has developed a Vibration / Noise in the last 2 Weeks. Its a light Vibration with a "drumming" Noise that repeats louder/ lighter. The Vibration is through the Floor not Steering. I have checked Brakes for Drag and Tires for Separation ( Radials). I pulled the Driveshaft Today to make sure new U-Joints were not tight and rotate freely and balance Weights are in Place. Motor / Transmission Mounts are new and Tight. The Vibration/Noise is diminished if I shift to Neutral . The only change I made recently was new Standard Mufflers and some Pipe bending. Nothing is touching the Frame. Any Suggestions?
