i know there are alot of exhaust forums in the search and iv read them. i dont want to buy a biturbo because its a poopie pipe for my a55. treats has a techno bullet for an a35. do you think i would be safe to not upjet with the techno bullet. because i called tomos usa and they said you dont have to upjet with a biturbo. of course everything else is stock, just exhaust. but biturbo is the only pipe that will work. since the techno and biturbo are similar, do you think it would be ok?
