Customer Review: (see review/s)
  • Came very fast. I ordered it round a lil before 1 on a tuesday and it was at my house friday morning. It was the right part and the price was way less than if I had bought it from a local auto parts store. Two things to know; you need to be sure everything that caused it to go bad has been fixed if not you will eventually kill the new one so get your check engine light off first. Clean out your egr valve if you didnt need to replace it might as well replace your pcv valve cuz its only $3 and clean out the area where its seated and if an O2 sensor is bad replace it the only two on this car (2000 model year) are right in the area of catalytic. Also if your flex pipe is bad you can just a flex pipe so you may be able to piece it together without having to buy the converter with the pipe to manifold. I ended up replacing or cleaning almost my whole emissions system to get it to pass the state test. With the help of this site and my own ingenuity what would have been over $500 in parts cost less than $140 not bad at all!!

Customer Review: (see review/s)
  • Had it installed quick and easy at the shop. It is a universal converter so it doesnt come with mounting flanges no universal does. You have to take it to a professional as there is cutting and welding involved to fit but thats what makes a universal cheaper. If you want a more do it yourself then get a direct fit converter. I went universal for the savings and it does the job just fine.
