Wagner Tuning BMW F-Series 35i Performance Downpipe Kit 7/13+

Unlock the full potential of your BMW N55 3.0 turbo with this high‑flow sports cat front pipe. Experience quicker spool, stronger mid‑range torque and a sharper exhaust note, all while keeping direct‑fit simplicity.

Built for 07/2013 onwards F-Series 35i models, this upgrade replaces the restrictive factory front section with a precision CAD‑designed, stainless steel SS304 assembly featuring a premium 200 CPSI metal substrate catalytic converter. Less backpressure means more flow, more response and more smiles every drive.
