I have a ZZP 3 in. catted DP made from 304 stainless. This is made for their shorty header. It has the extra O2 bung. It has been used for less than 6 months and was only used in the summer. I am looking for a ZZP 3in. catless DP for the shorty header. 304 stainless would be a plus.

 

i have a catless DP from ottp its full 3" i dont know if that would work for you?
