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
Maximise the exhaust note of your BMW M2 G87 (non-OPF models) with the Milltek Sport Secondary Cat-Back Non-Resonated Exhaust System. Engineered for non-OPF G87 variants, this system replaces the exhaust from the secondary catalyst rearwards with non-resonated stainless steel pipework — delivering a loud, dramatic, and fully uninhibited exhaust character from the S58 twin-turbo engine.
Without a resonator to dampen the exhaust note, this system produces the most aggressive sound available from a secondary-cat back upgrade — ideal for track use and drivers who want the maximum acoustic transformation. Available in five tip finishes including the exclusive Burnt Blue Titanium option. A direct bolt-on OEM replacement — no cutting or remapping required. Manufactured from 304L stainless steel at Milltek Sport's UK factory.
Fitment: BMW M2 G87 (Non-OPF/GPF models)
Race product: Yes
Tip options: Polished, Cerakote Black, Titanium, Burnt Blue Titanium, Carbon Fibre
