944S2,968 Stage 2 Header System

Every SFR header is TIG welded with 308, or 347 filler rod, on specially designed jigs. These jigs allow for a precise fit with no clearance issues. Every SFR header uses a special slip-fit merge collector that allows each runner to expand and contract without cracking. We can also upgrade the the headers to utilize double slip-fit collectors for dedicated race cars.These slip-fit merge collectors are also designed to use the proper angles to promote maximum velocity which means you get increased spool-up. Every SFR header is hand-finished on the inside for optimal flow and maximum performance.All 321SS SFR headers are guaranteed not to crack! Our 4 into 1 headers also come with the appropriate fittings for your stock or aftermarket wastegate and your O2 sensor. We can also weld additional fittings for EGTS's and wide-band O2 sensors. SFR headers can be ordered in a variety of primary runner sizes to suit your application. Each header/crossover also comes with 2 V-band clamp assemblies.We can also build these headers in Inconel for the most extreme race applications.
