"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." posted by: Kyle on August 10, 2012

"The 'minor modifications might be required' in the description of this item cost me an additional sixty dollars in labor and parts by a muffler shop. Had I walked away from the shop to call or write to Autopartswharehouse, my engine would have still been in peril due to further delay. 'Performance' is not rated. It takes time to determine a part's performance. How long it lasts counts." posted by: Lengo on May 30, 2012

"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
