Sounds like a restricted exhaust system. First check for crushed or damaged exhaust pipes or muffler. Are you also experiencing loss of power or the engine running hot? Those are other symptoms of a restricted exhaust system. Is the check engine light on? What year is your Silverado? If nothing is visibly damaged you may have a clogged catalytic converter or the baffles inside of the muffler may be falling apart and clogging up the exhaust system. HTH. -Jim
