"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." posted by: Doc on December 11, 2010
