Just ordered (from Hal) HK'3s ,K&N filter, crush gaskets, DynoJet kit, and Brown County Airbox cover, should be here by the end of the week. ( It's cool how they better any deals you find on the net.) Do I need a torque wrench, or any specific tools for the pipe install? I'll install the pipes, filter and cover myself and have my local HDL do the jetting. Thanks for any and all advice.
