Single Turbo Downpipe Exhaust For 2011-2012 BMW 135i E82 E88 E90 E92 N55 B30
Experience the perfect blend of quality engineering and exceptional value with these high-performance Downpipe. Manufactured from durable T-304 stainless steel with precision CNC-machined flanges and TIG/MIG welded construction, they deliver superior durability and flow characteristics. Computerized mandrel bending technology ensures smooth exhaust airflow for improved scavenging and reduced back pressure.
Features:
- Designed exclusively for the BMW 335i, this high-performance downpipe is precision-engineered from premium T304 stainless steel and expertly TIG welded in-house to ensure superior durability, corrosion resistance, and long-term performance under extreme conditions.
- Constructed with mandrel-bent tubing to maintain a consistent internal diameter, optimizing exhaust gas flow velocity and minimizing turbulence, which results in improved turbocharger efficiency, enhanced power delivery across the entire RPM range, and preserved mid-range torque.
- Features laser-cut flanges ranging from 10 to 12mm in thickness, providing exceptional structural integrity, perfect alignment during installation, and a secure, leak-free seal that enhances both reliability and performance while ensuring OEM-level fitment.
- Replaces the restrictive factory catalytic converter with a UK-fabricated de-catalyzed design that significantly reduces exhaust backpressure and lowers exhaust gas temperatures, allowing for increased cylinder charging, faster turbo spool, and sharper throttle response—transforming driving dynamics into a more immediate and engaging experience.
- Delivers measurable performance gains including noticeable increases in horsepower and torque, accompanied by a deeper, more aggressive exhaust note that amplifies the vehicle’s sporty character without compromising refinement, all while offering substantial weight savings over the stock unit to further improve handling and acceleration.
