Customer Review: (see review/s)
  • I really have no pro's or con's about this converter. Ordered it on Thursday and by Saturday I have FEDEX delivering the package. Really fast prompt service. It does not say this in the description of the product, but the openings are 2.5 inch inside diameter. Installed it today and so now I can get my truck inspected. I am forwarding this website to a friend of mine who has a 89 Chevy like my 92 and he needs a caty to get his truck running and inspected.

Customer Review: (see review/s)
  • CATALYTIC CONVERTER WORKED PERFECT WASEASY TO INSTALL AND WAS A GOOD PRICE.

    posted by: ART. on June 11, 2014

  • Getting the vehicle to pass smog was easy after having the catalytic converter installed. The hardest part of this whole repair was finding a shop to do the installation. A few calls and a trip across town and the install was completed in one day. No additional parts were needed and that was good on the budget.
