I have had a noticable increase and change in engine noise since the install. Do the pulleys create this or do I need to look somewhere else?

Is it an engine noise or belt noise? Better yet, what kind of noise do you hear? I installed N1 lightened pulleys in my car before. I didn't hear any noise at all. My car actually ran quietter and smoother.

The engine just sounds a bit raspier and more agressive.

I didnt hear any difference after installing my N1 set. Maybe something is loose?
