Wagner Tuning BMW E-Series Diesel Catless Downpipe Kit

Track-ready exhaust front section for BMW M57-powered models

Unlock stronger mid‑range shove and sharper response with this German‑engineered de‑cat front pipe designed for the BMW 3.0d twin‑turbo and single‑turbo diesel platforms. Crafted from high‑grade 304 stainless steel, this direct‑fit, bolt‑on upgrade replaces the restrictive factory unit to reduce exhaust backpressure, lower turbine heat stress and let your straight‑six diesel breathe as intended on track or off‑road.
