first question is if the drilled and slotted rotors are worth it or not the next is where i can find the best prices another question is if the original exhaust tends to make weird noises due to debrisinside...please and thanks for the help

 

Slotted and drilled rotors are worth it only if racing is in mind. The average driver won't feel much difference than OEM rotors, and in my opinion, only look good on a vehicle with low profile tires and chrome wheels. I'd much rather take the money that a rotor set would cost and put it into engine mods. And stock exhaust systems are designed to last the life of the vehicle. However, this does not make it true. Over time, pieces of the honeycomb in the catalytic converter may get broken and you could hear a rattling noise.

 

Yea, that happened to me when I had my 3.4L engine replaced years ago under extended warranty service -- the cat had broken up, and was replaced w/high-flow cat...
