the manual perfers you use 91 octane or higher. It also says you can still run 87, 89 octane in the car but you could notice some decrease in performance. I personally use the 93 octane in the car b/c i perfer to give the motor what it needs.
As for exhaust, there are tons out there. I have a magnaflow catback system on my car. It is perfect for what you descibed. It is not loud and raspy when on the higway just crusing and you can have a conversation in the car. But once you step on it, the thing roars.
