Hello

I am going to get a set of hearders in a week or two i was thinking about getting the edelbrock for the 97 z28 with dual cats but alot of people on here don't like them. I was also thinking about get the jet hot mac headers alot of you guys like them. My question is what all do i need to do to change over to the MAC header on a 97 z28 with the dual cats??? I already have a Borla Cat back on the car. So haw is the 94-96 headers going to fit with that cat back i don't want to get rid of it i love the sound of the car just looking for a little bit more. also can i use one of my 2 cats o got know or just buy a high flow?? I was wanting to keep the emmisions that what this all comes down to

Thanks
Shane
