i have a 2003 priaire 26bearclaws and a full skid plate the next upgrade i was thinking is the new modular box from dimond g. I don't have aftermarket pipe or filter or snorkel or jetting. Does anyone know if i need or should do this stuff first before i buy the dimong g modular box? thanks in advance for the help . Dale

 

No jetting changes are needed with the modulator. Your most noticable bottom end gains will come from this unit. You won't need a pipe or anything else before adding the module.
