2GR-FKS 304 Stainless Steel Header Collector Pipes with Sport Cats

The PPE Engineering header collector pipes are performance-oriented exhaust components for Lexus IS350, GS350, and RC350 RWD vehicles equipped with the 2GR-FKS engine. These pipes are crafted from durable 304 stainless steel, featuring 2.25-inch mandrel-bent tubing with robust 3/8-inch thick head and outlet flanges. The design includes formed collectors with an option for spike or parallel merge collectors, and equal-length tubes to optimize exhaust flow and performance. The mandrel bending process maintains the tubing's inner diameter throughout, preventing performance-robbing restrictions. These pipes come with integrated non-EPA compliant sport high-flow catalytic converters. PPE Engineering claims a bolt-on gain of 16 wheel horsepower (whp) from this system, estimating an increase of over 19 horsepower at the crank. Optional ceramic coatings are available, which can enhance aesthetic appeal while providing thermal barrier properties to potentially increase power and reduce under-hood temperatures. This product includes necessary gaskets and instructions for installation. The manufacturer offers a 1-year warranty on these header collector pipes.
