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
Enjoy a more sporting exhaust note without sacrificing day-to-day refinement in your Porsche Cayenne 958 Turbo (4.8L V8 Pre-Facelift) with this Milltek Sport Cat-Back Resonated Cup Style Exhaust System. The resonated configuration delivers a richer, more characterful V8 sound than the factory system — with reduced drone at motorway speeds compared to a non-resonated alternative. Finished with distinctive Cup-style tips for a sporting visual upgrade.
Direct bolt-on OEM replacement — no modifications required. Manufactured from 304L stainless steel in the UK by Milltek Sport.
