This downpipe improves flow by 20% compared to the stock pipe, making it perfect for high-performance or competition settings. Additionally, the included heat-wrap helps insulate the engine bay, lowering overall temperatures and enhancing heat retention where it matters most. Since the downpipe also includes a gasket, installation becomes more straightforward and ensures a proper seal. Importantly, this performance upgrade does not interfere with emissions systems, allowing for compliance without sacrificing power.
