Product Details

MagnaFlow’s Direct-Fit CALIFORNIA OBDII CONVERTERS line is built for emissions-focused replacement work where exact fitment and CARB compliance matter. Part number 4481458 uses a compact, low-mass design and factory-style geometry to match the original exhaust layout more closely than a universal converter. The stainless steel construction and OE-inspired spun body help support durability and thermal efficiency, while the bolt-on configuration simplifies replacement on the specified Toyota Corolla, Toyota Matrix, and Pontiac Vibe models.

This part cross-references MagnaFlow 4481458 for the same application.
