Bos T-Six Aluminium

A BOLT-ON bracket keeps the Bos T–Six free of the usual strap, so it looks clean and neat. It fits easily and feels secure and the good looks extend to a big-bore link pipe. There are carbon or titanium versions at £349 and a high-level link pipe option. Internals are stainless steel and a repair kit is £29.99. An increase of 5-10bhp is claimed. A road-legal version costs £314.99.
