PPE engineering Lexus ISF race headers - Polished ceramic coatin

The PPE ISF Headers make a significant increase in flow compared to the stock manifolds. Tube lengths and diameters are increased coming together into a ported 4-1 parallel merge collector. Completely TIG welded construction with thick 16 gauge tubing for long lasting power gains. Optional high-flow stainless steel ECT cats are an option. They get welded into your stock or aftermarket midpipe. The headers with no cats show a 38-46whp gain The headers with high-flow cats show a 28-33whp gain Our new design does not need to relocate the dipstick tube, it fits with the stock dipstick tube. Our headers come with Evolution Performance Ceramic Coatings that add good looks along with thermal barrior properties that increase power and lower engine bay temps. They are also a great protection against corrosion. The finish will stay looking great longer than a stainless steel header and perform better.Available in Polished or the Black Race Coating Header Features: 3/8" thick head and outlet flangesMandrel bent 16 gauge tubing15 degree parallel merge collectorsRunners are welded with Silicabronze at the head flangePorting at flangesFlat sanded head flangesCeramic coated mild steelLarger factory style gasketsIncludes O2 sensor extensions, O2 Simulator, gaskets1yr warranty Magnaflow Catalytic converters are EPA and OBD2 compliant.
