I am ordering parts late tonight and i am looking for some help. I want to go with dejon piping. I want upper, lower and whatever else i need. I heard that you should get there upgraded couplers. not sure what parts is which i know sounds stupid just dont want to order the wrong thing.

I want to order my dp tonight. I would like to go with zzp just not sure what i should get. I want the power but in NY there are bastards for inspection. I am not sure if i should keep the cat or not. Little help on that.

Thank you for help

 

If you have inspection in your state I would get the ZZP with the magnaflow cat. Right now CIA is selling there SS DP for the same price as ZZP's, so thats a alternative also. Both are good choices.
