Would like to upgrade your existing turbo header to the SFR "UltimateFlow" exhaust manifold? Not a problem. .
The heart of the SFR turbo system is our "UltimateFlow" 304SS (321SS is an option) exhaust manifold. This is not the typical log type of exhaust manifold that every other company is using in their kits. These are hand-made at our shop out of the best materials possible. These headers are built on special jigs and TIG welded. After they are welded, they are hand finished on the inside for ultimate flow. These headers will outflow any other log manifolds in existence!
