I'm thinking about buying a 95-97 LT1 Bassani Exhaust System True Dual System.I am wanting to know if I will need 2 catalytic converters for this system? And how does the headers hook up to this exhaust? I am also going to replace my factory headers.What will work best with this setup, short or long headers? I just bought my camaro and I am new to these kind of mods. I'm just wanting to make sure I get all the right parts for the setup I want, without having to buy any unneccesary parts or not buying the right parts to work with this exhuast. Thanks for the help.
