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
Restore and enhance the legendary air-cooled soundtrack of your Porsche 911 (996) Carrera or Carrera S with this Milltek Sport Cat-Back Cup Exhaust System. Inspired by the factory Sports Exhaust (Cup) option, this system delivers the distinctive, free-revving exhaust note that classic air-cooled 911 ownership demands — but with the quality and longevity of Milltek Sport's 304L stainless steel construction.
A direct OEM replacement designed to bolt straight on without any modifications. Made in the UK and backed by Milltek Sport's renowned build quality.
