This ETS Equal Length Manifold is used in our front facing v-band turbo kits or standard v-band turbo kits. All ETS Manifolds are built to last and backed with a lifetime warranty. We use the same type of material and constructions on our customers manifolds as we do on our own 1100whp Evo 8 manifold, 900whp Civic Manifold and 800whp Evo X Manifold.
