Bought a bung to put in the exhaust system for a dyno tune after some mods. Where is the best place to put it? From what I understand its better before the cats. I have random tech cats on my mac headers. Is it ok to put one behind the cats like in the I pipe??

Thanks

Best spot is before the cats. Since you're only putting one on there just pick a side and put it near the front O2 spot (I would go a little further away from the collector than your stock front O2 though).
