WHY IS MY MAKING A LOUD NOISE AND SHAKING WHEN ACCLERATED?

1995 Buick Century • 15,000 miles

My 95 buick century is making this loud noise. It sounds like a old chevy truck! I got new o2censors, catalyac convertor, muffler and pipes! Why is it making that noise and it shakes when accelerated over 50 mph.

Sounds like a old chevy truck rumbling. Like motor or exhaust rumbles

Only thing I can say is that it is too vague of a description. Have someone at a shop listen to it and get back to us with your findings

You may have a plugged cat do you ever have to let up on the gas for it to shift to the next higher gear?
