English manufactured 304 grade stainless steel head pipes for the Triumph Bonneville.
Not fitted with threaded holes for emission test
No catalytic converters
OD 42mm but will fit earlier carb 38mm type
These highly polished header pipes will fit all spoke wheel Bonneville models. The slightly larger diameter gives a more traditional look on the earlier carb models. On EFI models you can dispense with the ugly and pointless lambda sensors without leaving the welded bosses which spoil the look. (the ecu can be programmed to switch them off).
Perfect for improving the looks of an older model with badly tarnished pipes, removing the cats on a version with cats in the headers or getting rid of the lambda bosses on an EFI bike.
