It would depend on what type of noise and where it is coming from. It could be there was a fault with the installation. The first spacer to go onto the shocks is tapered and if it was incorrectly installed, the outer casing would rub against the shick causing the noise. Jack up vehicle and check the absorber housing for scratches and note if the external sleeve is brushing against the shocks.
You don't need OEM shocks but if the shocks you bought are defective it would be a different story.
