will a set of bbk longtubes properly bolt up to a mac prochamber? im thinking of running this combo but i dont want to deal with leaks. anyone here tried this before?
everything i've heard about mac headers says they're pure crap. i have owned a set of bbk's in the past and was 100% happy with them. as for the prochamber, i like the way it sounds.
the collectors on the mac are further apart than bbk. thats why mac headers work for autos and bbk doesnt. if you look at the vrx x-pipes for longtubes, they have different part numbers for bbk and mac
