S58 Stage 2 Bundle

The S58 bolt-on foundation, bundled: our 3″ catless race downpipes, the aluminium charge pipe kit and the bootmod3 Ultimate tuning licence for the G80 M3, G82/G83 M4 and G87 M2. Choose Stage 2 + Intake to add the S58 cold air intake as well.

Why it’s built this way

• Everything Stage 2 needs — the hardware and the map, together.
• Charge pipes included — replaces the factory plastic pipes, a known weak point under boost.
• Tune included — the bootmod3 Ultimate licence is in every kit.
• Saves $410 against buying the parts separately, on either option.

In the box

• Catless race downpipes — 3″ mandrel-bent, TIG-welded 304 stainless, CNC-machined flanges, OPF / GPF compatible
• Charge pipe kit — TIG-welded aluminium, replaces the complete factory charge pipe set
• bootmod3 Ultimate licence — cloud flash from your phone, the full Stage 1 and Stage 2 map library, custom tuning through the bm3 Tuner Directory, fully reversible to stock
