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
Constructed from Lightweight High-Grade Titanium – with complex parts made in Akrapovič’s in-house foundry – the Evolution Line provides a weight saving over the stock system, and increases power and torque throughout the rev range. The Evolution Line (Titanium) has been designed to meet ECE type approval as a plug-and-play system and fits directly onto the BMW X5 M’s stock downpipes. It is tuned to provide a perfect sound accompaniment to the car’s sporty feel, and is perfectly finished with hand-crafted Carbon-Fibre tailpipes to offer a beautiful visual appeal. The distinctive round design tailpipes have titanium inner parts to make them stand out from the crowd even more. The tailpipes have been impeccably crafted and designed to fit seamlessly with the optional Carbon-Fibre diffuser. It is also available with the optional Akrapovič Sound Kit.
