The ultimate part for making exhaust manifolds for maximum performance. Featuring smooth transitions, and exact dimensions for the best flow possible. This translates into less back pressure, and means more power with the same boost, or the same power with lower boost (and less lag)!

This CNC billet turbo collector features chamfered entry and wastegate pipes to make welding as simple as possible. This ready-to-weld part cuts hours or days off your exhaust manifold build time, and gives you a much better exhaust manifold!
