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
Transform the exhaust character of your Porsche Cayenne 958 Turbo (4.8L V8 Pre-Facelift) with this Milltek Sport Cat-Back Non-Resonated Cup Style Exhaust System. The non-resonated, Cup-style configuration delivers a bold, uninhibited V8 exhaust note — removing the factory silencing for a louder, more dramatic sound that reflects the Turbo's performance credentials. Finished with signature Cup-style tips.
Direct OEM bolt-on replacement — no modifications required. Manufactured from 304L stainless steel in the UK by Milltek Sport.
