Review on OE Replacement New Exhaust Manifold Catalytic Converter (674-933) for 2007-2012 Nissan Altima 2.5L L4 with Hardware (Replaces OE Part: 14002-JA91E) by Eddie Simpkins

Update after 3 months. The same problems occur. Check low fuel consumption and engine gauge. This time I went to the mechanic to install a proper cat converter. Good product. Excellent stuff. Solved my engine problem immediately. All the reviews that it doesn't fit perfectly are true, but that's to be expected as these parts aren't made directly by Nissan. It takes some patience and some pushing and pulling on the heat shields to get everything lined up, but it all works great. 100% satisfied with the product
