Due to a shortage of affordable options when it comes to trumpets or ‘bellmouths’ we are now producing our own design lightweight aluminium trumpets with standard Jenvey/Weber flange fitment. These are also compatible with our GSXR throttle body conversions when used with our CNC clamp ring design (see pics). Available diameters (internal) are 40mm, 45mm and 50mm. Lengths 50mm or 90mm. RRP £15 each.
