If you want to keep the OEM back box but get a better B pipe its Spoon you want, as it works with the OEM BB and is also a great piece of kit. Although you will pay a good price for a Spoon one, but alike all things the good stuff is always expensive.
PM Lecurie as he was selling Spon B pipe not long ago, maybe he still has it.
Same applies for the mani, I have a TODA one and its a amazing poece of kit. The DC sports headers are considered to be verg good and give good gains for half the price of a JDM one.
Best get searching the for sale threads mate
