onto the tube the resonator chamber can include upper and lower tube mount structures that can be hot plate welded and sandwiched onto the projection in the tube thus the tube is are positively retained in position with respect to the resonator chamber such that the tuning of the resonator does not change due to fluctuations in geometry of the tube and resonator chamber structure and such that there is little or no vibration noise and or possible damage that might result if the tube were free to move with respect to the resonator chamber application_number US 93916107 A description referring to the drawing figures like reference numerals designate identical or corresponding elements throughout the several figures fig1 illustrates a perspective view of an exemplary embodiment of a resonator assembly 100 made in accordance with principles of the disclosed subject matter the resonator assembly 100 can include a resonator chamber 130 that is connected to both an intake tube 110 and an exhaust or outlet tube 120 the resonator chamber 130 can include a plurality of mounts 140 and corresponding attachment structures 142 for mounting the chamber 130 within the vehicle for example to the engine vehicle frame or other vehicle component the extension mounts 140 are configured to receive the attachment structure 142 such as a bolt screw clamp etc the attachment structure 142 can be.
