RR Racing has been evaluating headers for Lexus IS-F for some time now. When finally choosing the headers to complement our ECU upgrade and supercharger for Lexus IS-F, we selected the best headers available on the market. 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.
According to our estimates PPE headers can make about 30 additional wheel horsepower compared to OEM manifolds with removed catalysts. If you buy headers with the tune package, then you can expect total power gains (including an exhaust) of 60-70hp over stock! Please refer to our ECU upgrade tune product for recent estimates.
Please note that the headers do not come with manifold gaskets. For older cars replacing manifold gaskets may be necessary. We offer these as one of the options with this product.

- RR-Racing recommends 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.
