BMW F20 F21 125i B48 rear silencer bypass delete, non-valved, GT-90 burnt titanium tips

Direct-fit axle-back for F20 and F21 125i models with B48 engines (2016 onwards). No valves, no flaps - just a louder, deeper, more responsive exhaust note.

• Non-valved design: simpler, lighter, more reliable than flap-equipped systems
• GT-90 burnt titanium tips: heat-treated blue-black finish, motorsport-grade looks
• Made in the UK from T304 stainless steel: corrosion-resistant and lightweight
• Fits factory M135i valance or diffuser - works on both 3-door and 5-door hatchbacks
• Retains OEM catalysts: emissions-compliant, no ECU remap required
