BMW M3 Touring G81 S58 Eisenmann Resonated Centre Pipe (Race)

Direct-fit resonated centre pipe for the BMW M3 Touring G81 with S58 engine. Replaces the factory GPF/OPF section with a race-spec, TIG-welded stainless steel midpipe featuring integrated resonance chambers.

• Engineered for bolt-on fitment with existing Eisenmann slip-ons or full downpipe-back systems
• Delivers deeper, more aggressive S58 exhaust tone while reducing cabin drone
• GPF and OPF delete - track day or fast road use only; ECU remap required
• No fabrication, no adapters, no guesswork - designed specifically for G81 M3 Touring chassis
