PURCHASE DISCLAIMER: RR Racing does not condone the use of emission defeat devices for any vehicles used on public streets or roadways. RR Racing will not tamper, remove, disable, or bypass emissions equipment on a motor vehicle in accordance with 40 CFR Section 86.1854.12(a)(3), Clean Air Act 40 CFR 1068.101(b). This includes software, known as tunes, that reprogram a motor vehicles electronic control module to alter engine performance and enable the removal of filters, catalysts, and other critical emissions controls.

Please note that this product is available as an option with the ECU Upgrade OBD Tune as part of a combined package at a discounted price!

RR Racing has been evaluating headers for Lexus IS250 for some time now. The PPE 250 Headers make an 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.

According to PPE estimates, these 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 to eliminate the raspy sound the IS250 makes with these headers, the exhaust needs to have either stock or high flow cats installed. Cat-less exhaust systems will make very raspy sound.

Header Features:

  • Comes with an optional RR Racing ECU Upgrade Tune package for increased power gain
  • Equal length tubing
  • Mandrel bent Stainless Steel 16 gauge tubing
  • 15 degree parallel merge collectors
  • Runners are welded with Silicabronze at the head flange
  • Porting at flanges
  • Flat sanded head flanges
  • Includes factory style outlet gaskets
  • Install instructions
  • 1yr warranty
  • RR-Racing recommends using ceramic coating or 2" wide titanium heat insulation with these headers.
