A triple-baffled muffler enables an engine sound that changes from very quiet when idling to louder as the throttle is pressed. The muffler provides three baffles which are hinged over the center of the muffler. The exhaust pressure travels through the muffler and pushes the baffles until they open

A triple-baffled muffler enables an engine sound that changes from very quiet when idling to louder as the throttle is pressed. The muffler provides three baffles which are hinged over the center of the muffler. The exhaust pressure travels through the muffler and pushes the baffles until they open to release the pressure. The angle of incidence of the baffles on their hinges governs the loudness of the sound.

The muffler of claim 1, wherein exhaust pressure travels through the muffler and pushes the baffles until they open to release the pressure. 3. The muffler of claim 1, wherein angle of incidence of the baffles on their hinges governs the loudness of the sound. 4. The muffler of claim 1, wherein two ring-shaped mounting plates are provided on the muffler, near the input end and output end of the muffler. 5. The muffler of claim 1, wherein the muffler is provided in a variety of sizes to fit any gasoline or diesel powered vehicle. 6. The muffler of claim 1, wherein said plurality of baffles is equal to three in number and said plurality of hinges is equal to three in number. 7. The muffler of claim 1, wherein said braces use springs such that said springs dampen impact between said counterweight and said brace when said baffler rotates to a closed position. 8. The muffler of claim 1, wherein said plurality of baffles move independently of one another. 9. The muffler of claim 1, wherein at least two of said counterweights are interlocked via a connecting bar; said connecting bar being attached to said counterweights with a mount such that said at least two interlocked counterweights rotate in synch so that said baffles associated with said interlocked counterweights also rotate in synch. 10. The muffler of claim 1, further comprising a plurality of shocks having a first end and a second end; said first end being attached to one of said plurality of counterweights and said second end being attached to a mount on said muffler; said plurality of shocks being configured to increase the resistance against rotation by the baffles. 11. The muffler of claim 6, wherein said braces use springs such that said springs dampen impact between said counterweight and said brace when said baffler rotates to a closed position. 12. The muffler of claim 6, wherein said three baffles move independently of one another. 13. The muffler of claim 6, wherein at least two of said counterweights are interlocked via a connecting bar; said connecting bar being attached to said counterweights with a mount such that said at least two interlocked counterweights rotate in synch so that said baffles associated with said interlocked counterweights also rotate in synch. 14. The muffler of claim 6, further comprising a plurality of shocks having a first end and a second end; said first end being attached to one of said plurality of counterweights and said second end being attached to a mount on said muffler; said plurality of shocks being configured to increase the resistance against rotation by the baffles. 15. A baffled muffler, comprising: a. a cylindrical muffler having a center line;b. a plurality of internal baffles;c. a plurality of hinges;d. said hinges being mounted within said cylindrical muffler along said center line;e. said plurality of internal baffles being attached to said plurality of hinges;f. counterweights;g. said hinges extending through said muffler such that each end of said hinge extends outside of said muffler;h. said counterweights being attached to the ends of said hinge;i. braces;j. said braces being attached externally on said muffler;k. said braces being positioned such that said counterweights rotation is stopped at a resting angle wherein said baffles are closed;l. at least two of said counterweights are interlocked via a connecting bar; andm. said connecting bar being attached to said counterweights with a mount such that said at least two interlocked counterweights rotate in synch so that said baffles associated with said interlocked counterweights also rotate in synch. 16. The baffled muffler of claim 15, wherein said plurality of baffles is equal to three in number and said plurality of hinges is equal to three in number.
