JSN Motorsport stainless steel downpipes

 Suitable for BMW 335i and 135i with N54 engine

 Including screws and seals

 Compared to the stock setup, the downpipes reduce backpressure and exhaust gas temperatures downstream of the turbochargers, thereby extending their lifespan. Additionally, the downpipes, when combined with software tuning, can increase performance.
 We also offer performance testing.
