80 mm Exhaust Sleeve Joint Clamp for BMW Turbo Six models

Restore a tight, rattle free join on your BMW centre section with this factory original 80 mm sleeve connector.

We fit these in our own workshop builds and the result is always the same, a clean seal, no blowing, no hassle. Customers love the OE quality, perfect alignment and long term reliability. Part number 18307560815.
