CAI and Exhaust

[Alister_McRae]

If i get a CAI should i go ahead and get new exhaust, or just leave it be? And if i get new exhaust, would it help any with the CAI, or hinder power?

The general rule of thumb is if you have a CAI sucking air in at a rapid rate, you want a better exhaust to let that air exit just as quickly. So, for the most part, a new exhaust will definitely help. Just make sure you don't get too big with the size of the piping or you will lose back pressure and that will hinder performance. Bigger pipe sizing is only good if you are planning on getting a Turbo or a Supercharger.
