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
After adding an Akrapovičfull Titanium Evolution system, you’ll never want to stop driving! The exhaust system is made of our proprietary Titanium and consists of dual-outlet mufflers with exhaust valves, flow-optimized pipes, and a unique cast X-shaped part with resonators. The Evolution lowers the back pressure and gives the M5more power without removing the catalytic converters. It increases responsiveness and offers a big difference in weight. Sound is improved too, with a deep sporty sound that grows to an aggressive roar when driven hard but still has no droning. It works well with the M5’s ANC system - just like the valve system, which is regulated through the M5’s settings. Complete the look with a set of four exquisite tailpipes in Titanium or Carbon Fibre.
