Stainless Steel Race Headers

The PPE Engineering 935001A-SS Stainless Steel Race Headers are engineered for performance enhancement on specific Lexus AWD V6 vehicles. Constructed from robust 304 stainless steel, these headers feature 3/8-inch thick head and outlet flanges for durability and precise fitment. The tubing is mandrel bent with 16-gauge material, and they include formed collectors with either a spike or optional parallel merge collectors for optimized exhaust flow. Installation is facilitated by included O2 sensor extensions, gaskets, and instructions. These headers offer a claimed power increase of 16 wheel horsepower (approximately 19+ horsepower at the crank), as documented by a dyno run on a Mustang dynamometer at ADS in Chandler, AZ, which showed gains of 16 whp with a total of 281 whp (approximately 336 hp at the crank). Optional ceramic coatings, such as Black Ceramic Coating or Cerakote Glacier Black Ceramic Coating, are available to enhance aesthetics, provide thermal barrier properties, reduce engine bay temperatures, and offer superior corrosion protection. A 1-year warranty is included. It is critical to note that these race headers are designated for competition use ONLY and are not legal for use on public roads or highways. Use on public roads may result in violation of the Clean Air Act and subject the user to civil penalties. Fitment is strictly limited to LHD (Left-Hand Drive) AWD models equipped with the 2GR-FSE motor. They will not fit Hybrid models or vehicles with the 2GR-FKS motor.
