the trumpets are made by emerald, however an important part of how they work is that fact the flare follows the age old weber 40 dcoe design, you cannot use the adjustable trumpet to decide on a length them use that same length on a more heavily tapered or full radius design.
at the moment the trumpets are only avaiable for 42 and 45mm jenveys, however they will fit 48's and 50's, obviously a 45mm trumpet isnt going to have as big a hole as a 48mm body, but as a 45mm tb will easily flow enough air for 260bhp i dont think fitting 45 trumpets to 48 bodies they will hold your engine back one bit.
4 x 45 adjustable trumpets are £135 plus vat and postage, i can discount that price down a bit if your interested in some

Looked like you were going well at Brands at the weekend Andy. It was good to meet you and David and the rest of your crew.
