he's right you can pick up a aebs for way cheaper and have it ported and port matched and pick up a nice throttle body and they work great.

but as far as off the shelf manifolds the performer x makes the most power for the money just make sure you pick up a 70mm or bigger throttlebody.

unless you have plenty of cash then you can pick up a endyne sheet metal manifold or a air carbon one.
