Customer Review: (see review/s)
  • Bought product and had it installed on a 2000 Nissan Altima. Saved over $500 dollars on part by not buying Nissan original part. Had to Cut a piece of the front heat shield from the car to fit, but part had its own heat shield so no harm done. I have had it on my car for over 2 years, and it still works great! Recomend to anyone who wants to save a lot of money over an OEM Nissan Cat. Converter. Shipping was practically free and customer service was great. Thanks for a great product!
