Stainless Steel Long Tube Headers

The Flashark Long Tube Headers are designed to enhance the performance of BMW's N52 engine by improving exhaust flow and providing a more aggressive sound. This system is specifically engineered for 2006-2013 BMW E90, E91, E92, E93 3 Series (128i, 325i, 328i, 330i) and E82 1 Series (128i) models, provided they have the factory N52 engine and are left-hand drive. Constructed from durable stainless steel with a mirror polish finish, these headers feature 1.50-inch primary tubes made from 16-gauge material and thick, CNC-machined flanges for a reliable seal. The long tube layout and mandrel-bent piping aim to optimize exhaust gas scavenging, which can lead to improved throttle response and a noticeable increase in high-RPM pull. Expect a sharper, more aggressive exhaust tone, especially when paired with a freer-flowing downstream exhaust system. Installation is considered moderate to difficult, requiring careful attention to fitment, O2 sensor routing, and potential mid-pipe alignment. It is recommended for experienced DIYers with proper tools or for professional installation. Buyers should be aware that these headers may affect O2 sensor readings and emissions monitoring, potentially leading to a Check Engine Light (CEL). A tune is often recommended to optimize performance, improve drivability, and reduce CEL risk. This product is not intended for vehicles requiring strict emissions compliance or a completely stock exhaust note. Crucially, these headers WILL NOT FIT non-N52 engine configurations, all Right-Hand Drive (RHD) vehicles, or engine-swapped/heavily modified vehicles. It is essential to verify your vehicle's exact chassis, engine, drivetrain, and steering position before ordering, as fitment is precise and not based on model badges alone.
