"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." posted by: sidekick on January 30, 2014

"My 1991 Honda civic was pushing 1800 ppm on Nox and I changed reworked everything but the cat. Failed it again and bit the bullet and purchased this cat as a last resort.I was nervous but was pleased to find the cat improved my nox value from 1800 to 03 at 15mph. Thats fantastic and was pivotal in my selling of the vehicle." posted by: Brandon on December 10, 2013

"Installed in a 91 Honda Civic Hatchback located in California. I was concerned because of my previous experience with a Bosal cat was not good at all but this one turned out to perform as expected. Here are the results from the smog check: C02 ......... 14.5 to 14.7 O2 .......... 0.3 to 0.7 HC(PPM) ..... 0.00 CO ........... 0.00 NO(PPM) ..... 6 to 323 The cat passed the inspection with excellent results. One important matter to ease your installation. Because of the way the intake flange is designed your OEM bolts will be too short. Plan on purchasing the following to replace the OEM bolts that fasten the cat intake to the cars exhaust pipe. 2 - 5/16 hex bolts that are 3 1/2 long Zinc coated. 2 - 5/16 hex nuts zinc coated 2 - 5/16 washers zinc coated 2 - 5/16 fender washers (at least 1 diameter) zinc coated Use the fender washers to hold the springs." posted by: Mr Foxcroft on April 4, 2013

"The catyltic convertor I purchased from Autoparts warehouse did the job. Sailed thru smog test after it was installed. What impressed me most was that I received the cat within two days of my order. Also I called and got advice and guidance from Autoparts support that was most helpful. I would without hesitation recommend using Autoparts to purchase any auto part that you need.Robin Davidson" posted by: Robin on December 13, 2013
