DESCRIPTION

This T304 stainless steel performance exhaust mid‑pipe is specially developed for BMW G80 M3 with S58 3.0T inline‑six turbo engine.

Optimized equal‑flow Y‑pipe design reduces exhaust back‑pressure, improves exhaust gas flow efficiency, brings better throttle response and richer exhaust tone. Comes with high‑temperature woven heat shield sleeve to lower under‑chassis heat radiation. Fully mandrel bent tubing and precise TIG welding ensure structural durability. Direct bolt‑on design, matches original mounting points, works well with stock or aftermarket cat‑back exhaust system.

The mid‑section adopts multi‑segment splicing structure with V‑band clamp connections for convenient installation and disassembly. The internal flow path is optimized for S58 turbo characteristics, eliminating flow bottlenecks of factory mid‑pipe. Compatible with both stock rear exhaust and valved cat‑back kits for flexible tuning combinations.

VEHICLE FITMENT

• For BMW G80 M3 — 3.0T S58 Inline‑Six Turbo Engine

KEY FEATURES

• Premium T304 Stainless Steel Material: Industrial grade T304 stainless steel construction, anti-rust and anti-corrosion for long-term chassis environment use.
• Equal-Flow Y-Pipe Optimized Structure: Balanced dual-into-Y merge design, minimizes exhaust back-pressure, enhances exhaust scavenging effect.
• High-Temperature Woven Heat Shield Sleeve: External wrapped heat insulation sleeve effectively reduces chassis heat radiation, lowers surrounding component temperature.
• Full Mandrel-Bent Tubing: Smooth mandrel bends without pipe flattening, keeps consistent inner diameter to avoid airflow turbulence.
