i just install ( HEADERS ) /// Afe FILTER // LAST 2 MAGNAFLOW MUFFLER .160 SLP thermostate , BASIC TUNE ,
also i remove the catylics converter .
now the car in perfect condition but my major problem is the strong smell in the exhaust . not inside the car only outside , that when i want to put anything in trunk i feel the smell strong ,

Any catalytic converter will cut or completely eliminate the smell. If you are concerned with performance, a high flow unit would likely be preferable, and better than no catalytic converter.
I have a high flow unit, and still have the smell when cold, but it goes away quickly as the car warms up.

No, direct fit may not work in your case. Take it to a shop that can weld one in directly.
You will need the upper O2 sensors, do not remove them, do not tune them out.
