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
Developed to be used in conjunction with the Akrapovič Slip-On Line (Titanium) and the Evolution Link Pipe Set (Titanium), this high-quality stainless steel downpipe set features a pair of sporty catalytic converters (200 cpsi) with heat insulation. The front part of the downpipes is cast in the in-house foundry, providing a perfect fit. Delivering a pure racing sound full of emotion, this provides great feedback at high revs, without drone. Remapping the ECU is mandatory to prevent potential check engine light warning signals. This product is meant for racetrack closed course use only.
This product fits on xDrive, CSL, M3 Touring (G81), M4 (G83) Competition and Convertible models.
