Catalytic Converter Replacement for 5.6L Rear Right & Left | 2004-2015 Nissan Titan | 2005-2015 Nissan Armada | 2004-2010 Infiniti QX56 | Direct Fit OBDII with Gaskets Included

The length and flange positions were correct but the pipe sizes are too large. These have a lip which is supposed to go inside the manifolds but they are larger than the manifold holes and the o-ring gasket will not fit over the pipes. We had to cut the pipes flat to the flange and use a flat gasket to get it to work.

Pipe was different size than factory, flanges didn't line up, bong holes for 02 sensors didn't line up. NOT a fit for my '05 Nissan Armada as promised. Took 17 days to get here, a trip to the mechanic which was a "BUST" since nothing fit! Terribly DISAPPOINTED!!!!!! I have pictures the mechanic took, but haven't transferred them to my computer yet...anyone wanting to see, just ask. I should have them up in a day or two.

2nd day since installed and so far no issues and truck runs great!

Perfect fitment on my 2005 nissan titan.great product at good price.

Great product! Direct fit, great sound

perfect fit easy to install
