I know a 2 1/2" cat back will bolt on to a stock 90 GT, will a 3" cat back bolt on as well? If not, what will I need to do?

Also, will a 3" cat back on a stock motor make the car lose some power? I know a 2 1/2" will build some power but I'm thinkin on a stock engine 3" might not provide enough backpressure.
