Honda Civic Si catalytic converter

Fits all 2012 to 2015 2.4L 4cyl models ONLY ( NOT for the 1.8L models ) This is THE BEST aftermarket converter on the market today. Nearly a direct copy of the OEM unit, features the proper inlet and outlet sections, not cut and paste designs of the others. LARGE body like the original! Just look at the outlet pipe, no other unit is designed to flow like the OE unit. Direct bolt-on, no cutting or welding required. 4 bolt inlet flange mounts to exhaust manifold. 2 bolt outlet flange, bolts to front exhaust pipe, has provisions to mount both factory O2 sensors. OBD2 configured converter core ensures no premature check engine light and long life. As all our converters, made in USA or Canada !
