High-quality downpipe for BMW F20, F21 M135i, M135iX models with N55 engine (PWG).
Exclusively crafted by KPerformance, our full 3″ (76mm) downpipe maintains a bolt-on fitment while maximizing exhaust flow and minimizing backpressure, resulting in sharper throttle response, increased performance, and a deeper, more aggressive exhaust tone.
