T-316 stainless steel headers from FVD produce dyno proven horsepower and torque as well as a phenomonal sound! FVD headers feature equal length, mandrel bent tubing and a merge collector to further improve exhaust gas flow, reduce system back pressure and optimize exhaust gas scavaging and cylinder filling. FVD headers are dyno tested and produce up to 15 lb ft. Of torque in the mid range where the 3.4l needs it most. Tech tip: for older cars repair-kit FVDmk996201

General Fitment

Only for vehicles with Porsche standard sports exhaust system 200 cell, hjs tri-metal, hf (high flow) hjs catalytic cores with "u-torque" design, manufactured by m in Germany. The u-torque design compensates for the backpressure loss while running the high flow cats. The design minimizes the loss of low end torque and adds 10-15 ft-lbs of torque in the mid and top range of the rpms. Why settle for the traditional cross over cat design when you can add more torque in the mid-range and minimize the loss of torque down low where the 997's need it most! Please note: these fit the OEM mufflers and Porsche sport exhaust (pse) mufflers. Tech tip:add one of our installation kits FVD mk 997300

This heat exchanger is engineered for the discerning Porsche 911 owner. Ssi heat exchangers are made from superior t 304 grade (18% cr, 8%+ ni) stainless steel. Ssi has become an industry standard for Porsche 911 heat exchangers due to the exceptional materials, craftsmanship and durability. This is critical when considering heat exchangers, as exhaust leaks caused by poor materials can lead to carbon monoxide entering the cabin via the heating system. Features: gains of +10-15 hp and +10-20 tq t304 stainless steel (18% cr, 8%+ ni) increased pipe diameter for backpressure reduction connects to "early style" dual inlet mufflers bolt on replacements reduces the thermal load on the motor includes custom torque w...(choose a part on the right to read more)

This sports exhaust system offers a fuller, more powerful sound for your 996 Porsche. The sound is pleasant and mellow at idle and low rpms; as rpms increase more exhaust is channelled to the bypass pipes thus providing an increasingly sharper and more aggressive tone. At just under 5k rpm through redline it is in full bypass mode giving an exciting sound similar to the club sport cars. The sound is managed by an electical/vacuum control system allowing you to operate in stealth through the neighborhood yet providing that unmistakeable pure Porsche sound as you power through your favorite twisties.
