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

2011 xterra pro4x, everything works but the downstream pipe on the passenger side is off. It wont line up if you had the original set up. Mine was cut off where it meets and welded by the previous owner so i had to cut again to remove the old one. For me it didnt matter if it didnt align coz ill need to bring it to the muffler shop to get it fix.

These are horrible. Need bent cut and persuaded to fit. And they didn’t even make It a year and are clogged again. Huge waste of money. Huge waste of time trying to install. And now I have to go to rock auto and do it all again not even 12 mi th later. Don’t buy these.

I installed this on my 2003 Honda CRV, I was able to get it installed however the bolts that bolt onto the header for the cat aren't the same size as the originals. I'd also say it's not very well built, you do get what your pay for, and if you've got some time and spare bolts laying around it'll work great for the price. Just keep in mind it may not 100% fit. The bolts on the side where it meets with the rest of the exhaust worked great, but the bolts that connect to the header do not fit. The threading is wrong. I'm not sure if they'd assume you'd replace the header as well, but I made it work. Even if a clamp is holding down one side, but you can thank salt for that. Installation was easy, I can't blame the rust for taking off the old one as that happens especially where I live. However, after installing it my vehicle was much quieter, I could still smell some exhaust so it for sure won't be on par with an OEM cat, but it get's the job done for sure. As I said, you got the time, parts, and tools, it's great for the price.

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

Perfect fit on my 2006 Honda Ridgeline.

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
