Catalytic Converter Replacement For 2005-2018 Frontier 4.0L, 2005-2012 Pathfinder 4.0L, 2005-2015 Xterra 4.0L Replace 16399, 16400, 16467, 16468 (EPA Compliant)

I like that it came with bolts and gaskets. The new bolts did not fit the vehicle exhaust manifold but I expected that so I used the original. It fit well with the new resonator I ordered to replace what was stolen. Build quality is good but time will tell with performance. Have not ran the engine yet, other things to deal with.

Buen producto

I ordered this and gave it to my mechanic to install. The kit did not fit correctly at all. My Frontier is stock with no modifications. I would suggest you not waste your time with this manufacturer if you have a Frontier.

Fits 2008 nissan frontier. Did bolt direct without modifying. I left one original stud on my manifold. Where the 2 new parts bolt together, I feel could've been a little better. I think the holes for their bolts were a little sloppy (I did put thicker washers on mine) but other than that the product was good enough for me, especially for the price. Side note, I think it does make my truck sound a little more throatie haha

Very cheap compared to other places and it does the same job

05 Xterra they did fit but had to cut my o2 sensor because the spots weren't in the right spot but if you don't have emissions they will work for you.

This catalytic converter system was a perfect fit for my 2014 Nissan Frontier 4.0L V6. And now my truck runs like new. Highly recommend this set.

Pipes were not welded correctly, had to cut flanges from pipes then reweld back on

Tuvimos que hacer una modificación al tubo de escape pero sin problema quedó bien y el código de catalizador sé apagó

I took it to the maffler shop he said it is the wrong bolts. Spring and joints are noy fit Jjst more headache on that Maybe i will think to leave my straight pipe on it

Todo quedo bien sin problemas me encanto

Se tapó mi catalizador en menos de 3 meses, no lo compren si no quieren tirar su dinero
