  • Who could have thought that shopping for a catalytic converter, could be so easy as 1,2,3. Well, it was. The magnaflow catalytic converter is the best purchase ever. With one entrance, and two escapes, makes the air flow faster. It's practical shape, makes the installation much more easier. What more can I do, other than recommend this piece to others.
