String Theory Garage will be closed to the public from Wednesday, 29th July to Thursday, 6th August for our annual shutdown.
If you need to get in touch, please leave us a voicemail or send an email. Our team will happily get back to you when we return on Friday, 7th August.
Shopping online? Don't worry! Our online store will remain active! We hope to ship orders placed for in-stock items as normal during the shutdown. Anything else will be dealt with upon our return.
Thank you for your understanding, String Theory Garage Team
Give your BMW M2 G87 the exhaust upgrade it deserves with this Milltek Sport Resonated OPF-Back Exhaust System. Specifically designed for OPF/GPF-equipped G87 models, this EC-approved system replaces the factory exhaust from the OPF/GPF outlet rearwards, unlocking a noticeably richer and more engaging exhaust character from the S58 engine — all whilst keeping the factory particulate filter in place.
The resonated design maintains day-to-day refinement and comfort at motorway speeds, making this the ideal daily driver upgrade for M2 G87 owners who want a genuinely improved sound without excessive cabin noise. Available in five premium tip finishes. A direct OEM replacement with no ECU remapping required. Manufactured from 304L stainless steel in the UK.
Fitment: BMW M2 G87 (OPF/GPF equipped models)
E-marked: EC approved
Tip options: Polished, Cerakote Black, Titanium, Burnt Blue Titanium, Carbon Fibre
