Catalytic Converter OEM Replacement

I bought these to replace cracked Nissan OEM exhaust manifolds. The fit and finish seems pretty good and they snapped in as they should. I hope they don't crack like OEM junk.

Don't be put off by the price!

The dealer charged $3000 to replace both sides of my 2006 Titan. I decided to order my own and have a reputable mechanic do the installation. I'm glad I did as the total cost of many was $1200. No issues or performance issues. I would recommend.

This time, choosing the cheap route didn't pay off.

Well I went the cheap route and decided to order this and the associated part (674-843 for the other side) for my Titan as the overall reviews were pretty good and it bit my butt . I don't mind the sloppy welds or the way the parts looked going into the engine bay and under the truck, but of the two, one ended up with a hole. In the store where I took it, they finally found a hole with a smoke machine, closed by one of the reinforcement plates. After the plate has been cut off, it looks like…

Pros
  • Certified
Cons
  • Slightly torn
