  • Perfect fitment!
The quality is excellent, and delivery was quick.

  • Fit vehicle BUT...
Ordered to replace bad convertor. Item fit the car perfectly HOWEVER the bolts provided DID NOT fit the lower flange, had to use alternative bolts and nuts. Appears to be a recurring theme. You would think seller and manufacturer would get the hint after bad reviews.

  • Great Quality, wrong bolts!
My original manifold broke right at the block and had sub par welds, looking online so many identical broken manifolds exactly like mine. I went with this one by name recognition and the weld quality was excellent. I would’ve given this a 5 star, but the bolts that came with it don’t thread into the flanges as they were fine thread instead of course, what’s weird is the bolts are supposed to thread into their own product!! ... show more

  • Doesn’t properly
I bought this doormans Catalytic Converter. When U received it the bolts were bigger than the size of the wholes and hence got stuck in the catalytic converter. The quality of the part was so bad that it was slightly crack. Pay $100 more but buy from the store. Sometimes online parts are not worthed
