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 our ECU Upgrade Tune is available as an option with this product at a reduced price (not for 2017 model years).

RR Racing has been evaluating headers for Lexus RCF for some time now. When choosing the headers to complement our ECU upgrade and supercharger for our shop Lexus IS-F, we selected the best headers available on the market -- and we decided it is even more true for the RCF/GSF equal length headers.

The PPE RC F/GS F Equal Length 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.

Although RR Racing has not measured power gains of equal length versus unequal length headers on the RCF, equal length headers have the following technical advantages over unequal length:

An equal length header will expel gases at an equal rate per pulse, with gas from each cylinder leaving the header at the same time. With an unequal length header, gas from the two longer runners will remain in the header as it will take longer to reach the collector -- this results in lower cylinder temperature on an equal length header, which can help prevent ringland failure. Another benefit of equal length headers is the balance of backpressure at the exhaust ports, which will improve volumetric efficiency and overall top end performance.

According to our estimates, PPE headers can make between 30 to 40 (38 to 45 with our tune) additional wheel horsepower compared to OEM manifolds with removed catalysts (based on RR Racing Dyno tests). Please refer to our ECU upgrade tune product for recent estimates.

The headers include new Lexus 60mm outlet gaskets and a dipstick relocation bracket.

Header Features:

  • Comes with optional RR Racing ECU Upgrade Tune package for increase power gain
  • 3/8" thick head and outlet flanges
  • Equal length runners
  • Mandrel bent Stainless Steel 16 gauge tubing
  • 15 degree parallel merge collectors
  • Runners are TIG welded with Silicabronze at the head flange
  • Porting at flanges
  • Flat sanded head flanges
  • Includes factory style outlet gaskets and optional engine gaskets
  • Install instructions
  • 1yr warranty
  • RR-Racing recommends either doing ceramic coating or using 2" wide titanium heat insulation with these headers. We also recommend keeping the heat shield to insulate the starter when the headers are installed.
