Our NEW Gen 2 b58 manifold is something no one has seen yet. This manifold features a modular elbow that allows for the turbo to be swapped across manufactures with just a simple vband. No need to change manifolds if you decide to go from a garrett smaller frame to a large frame precision unit. This makes changing the turbo an absolute breeze as well as saves you a ton of money! Perfect for those that want a large frame turbo for track use but a streetable turbo for cruising around town. The down pipe is 3.5in and connects to the factory exhaust. Lower charge pipe is included in the hot parts kit.
