I have a 91 Z28 350 TPI dual cats. I want to get hedders and full cat back. If i get 15/8 hedders and a 3" inch catback will I have a problem hooking it up to the cats, or will it be a direct bolt on. Also can anyone tell me where I can find the cheapest set of hooker or hedmann hedders for my car and what would be a good size to get and what are the emmision controlled hedders called A.I.R.? If anyone can answer this soon, I would appreciate it. I would like to order this today. Thanks for you help.

 

I would also like to know does anyone know if hooker makes a direct bolton catback for dual cat cars. With hedders and this catback will it be loud or still quiet?

 

I would call Jegs, they should be able to answer that, or maybe they have one that will bolt up to the stock cats that they don't list in the catalog.
