I have been doing some shopping around with exhaust system and have pretty much decided that I am going to go with the Greddy Headers and Greddy TIC Exhaust system for my EX D16Y8 Sedan only problem is deciding on a cat converter. I am trying to avoid a very ricey sound and I know the cat helps resonate that, so test pipes are not an option. I have 2 new NTK oxygen sensor already to go on also. So what would be the best cat match for me? (Naturally Aspirated, 55 Shot Zex) Many aftermarket mods...
