Motorsport quality for the ultimate durability and power on the street and track! Developed and tested to survive the grueling environment of endurance racing. Shorter length headers tend to crack on cylinders 3 and 4 under the higher heat and vibration at the track. Shorter pipe length does not have room to expand like a longer tube header which causes the cracking. Our double push-piece design on cylinders 3 and 4 allows the shorter length header to expand under these conditions and prevents cracking that has always been an issue on cylinders 3 and 4. FVD Brombacherheaders are the only headers on the market which feature this innovative design ensuring years of trouble free operation. Through countless hours of research and development, FVD has found the ideal performance header combination. FVD headers reduce exhaust backpressure and temperature without sacrificing velocity to ensure optimal turbocharger boost. Our headers feature a 42 mm primary tube that empties into a 50 mm (id) collector. Too large a diameter on the primary will effectively reduce back pressure and exhaust temperature, but consequently lower the exhaust gas velocity and reduce performance. Bigger is not always better. FVD headers provide maximum flow, optimal cooling and maximize your performance. Our latest FVD Brombacherheaders also include a motorsport style merge collector that is extend internally for smooth, laminar exhaust flow. Our headers are manufactured from the highest quality t-316 stainless steel which is more corrosion resistant than t-304 and produce dyno proven horsepower and torque! Made of v4a (t316) stainless (more corrosion resistant than t304). Tubing features a merge collector to channel exhaust gases for maximum torque gain! Gains 15 lb. Ft of torque. FVD 's 997 tt headers weigh 11lbs.
