RR Racing has been evaluating headers for Lexus IS350 for some time now. The PPE 350 Headers make a significant increase in flow compared to the stock manifolds. Tube lengths and diameters are increased coming together into a ported 3 to 1 parallel merge collector. Completely TIG welded construction with thick 16 gauge tubing for long lasting power gains.

According to our estimates PPE headers can make between 10-16 additional wheel horsepower compared to OEM manifolds with removed catalysts. Please refer to our ECU upgrade tune product for recent estimates.

Please note that if you do not chose the ECU upgrade option package, then we can provide the RR Racing O2 simulator at no additional charge, but you need to select this option with your order.

  • Comes with an optional RR Racing ECU Upgrade Tune package for increased power gain
  • Equal length tubing
  • 3/8" thick head and outlet flanges
