great responses guys this is what I was looking for....I already bought the sort ones, but wanted to make sure that they would work........

 

Well it looks like FAILURE......the HKS Hi Power Exhuast does not have room for even one Short Fouler.......this sucks........I have had this Dynamic Design o2 simulater sitting around, and I just found the shop that knows how to install it. So I have a set of Foulers already CLEANLY drilled using 1/2 inch bit....if anyone want its it, it's 6 bucks shipped.

 

I have a similar problem, the spacing is so tight when I drive it hits the floor like crazy making me nuts, so I had to take it off. I think I have to go and move my lazy brain to make some kind of emulator. There has to be a way for it to work the way it should.
