Unleash the hidden potential of your Lexus Is250 with the performance-engineered PPE 250 Headers. Specifically designed for the Lexus IS250, these headers are a significant upgrade over the stock manifolds, promising enhanced exhaust flow and a noticeable boost in horsepower. If you’re looking to maximize the performance of your IS250, upgrading your headers is a crucial step, and the PPE 250 Headers are an excellent choice.
The PPE 250 Headers are meticulously crafted to optimize exhaust flow for your Lexus IS250. Featuring increased tube lengths and diameters, these headers are engineered to efficiently channel exhaust gases away from the engine. This improved flow is achieved through a design that converges into a ported 3 to 1 parallel merge collector, a key element in maximizing performance gains for your IS250.
Performance estimates from PPE indicate a potential increase of 10-16 wheel horsepower when replacing the OEM manifolds with these headers, especially when catalysts are removed. For the most accurate and up-to-date performance figures, we recommend checking our ECU upgrade tune product, which is designed to work synergistically with these headers to further amplify the power gains in your Lexus IS250.
It’s important to note that while these headers enhance performance, the Lexus IS250 can produce a raspy exhaust note when headers are installed. To mitigate this, we recommend maintaining stock catalytic converters or installing high-flow cats in your exhaust system. Cat-less exhaust configurations with these headers may result in a noticeably raspy sound that some drivers may find undesirable on their IS250.
