The 3 bolt design exhaust manifold, and up pipe (AKA the GT Spec GEN 2 in the USA, and the Tomei Extreme in Japan) has built a reputation based on it's consistently excellent performance results, and fantastic build quality.

This is why it is the most recommended exhaust manifold kit for cars aiming for 380bhp, and above, giving excellent spool up, and lifting power, & torque all the way through the mid', and top end.

Manifolds are supplied with all manifold, and turbo gaskets, nuts, bolts, studs, and a 50' x 2" roll of exhaust wrap - everything you need.

These exhaust headers are slightly unequal length to retain the Subaru burble but still gain maximum torque/power.
