Are there any parts available ie cat-back, intake, ecm upgrade, smaller pulley or anything else for some power? I just got the car and hope i can get it a little quicker thanks

 

I am in the process of buying a 1999 millenia S and have only found a drop in K&N, and lowering springs. Amazing how few parts ther are for an engine that could make a lot more hp easily with basic parts like ecm, pulley, cold air intake, and FMIC.
