  • I ordered this catalytic converter for my 4runner. I had it professionally installed. Within days, my check engine light came on. This part was defective from the start. I am extremely inconvenienced because even though it is under warranty, I will have to pay another $300 for the new one to get installed since labor is not included in the warranty. I will never purchase this part again!

  • The hard part is getting the old one off. that s not even hard. The only thing you ll need is some new bolts to hold your new converter on. I was wondering and nothing says or no one tells but it does come with the gaskets. Even the ones for the o2 sensor. took care of the engine/o2 sensor light error code.

  • I had to replace the entire exhaust system on my Toyota tundra. after about ten yrs old it needed it. I could not buy the resonator from you but the two converters and muffler were the direct fit kind. although I was a little surprised at all the welding that was done everything was in the right place. it took a little tweeking to align everything up all the parts fell into the right place. it was a one man job. worse part was getting the pieces out of the hangers. you amazed me with your prices and quick delivery. I will recommend you to everyone that needs parts.. thanks

Customer Review: (see review/s)
  • While it is necessary to adapt to pipe size on vehicle, the rear requires leaving part of the previous converter on. i.e. The very end of the old converter. That will be the same OD as the new converrter. The old fitting has to be ground down, or as I did, filed. I might better have used a coupling. When I do the left bank, I may try cutting the old portion off, and adapt down. I shall try the coupling. You must have a local supplier who stocks a wide variety of fittings! They are inexpensive. Remember, the adapters can be shortened to allow slippage while installing. They can always be shortened, but cannot be lengthened once cut off, so measure carefully. Think ahead. Procrastinate. As it is, I am still going to have a friend braze the rear end joint, as it leaks a little. Using a coupling most likely would have avoided the leakage.
