Civic exhaust manifold
This manifold was an excellent buy. Installation was straight forward. The quality and the value were first rate.. The only real difficulty I had was getting the old original manifold out. I shopped around for a long time and most of the other places prices were much more. I'm convinced you won't get a better deal on a new converter anywhere than 1A auto

Great product
This same product at local auto parts stores was around $400. Why pay that much when they both have the same warranty! 1AAuto was extremely fast and friendly. I ordered this on a Wednesday morning and by Thursday afternoon it was on my door step. After clearing the check engine light after replacing the cat/exhaust manifold I have driven well over 1000 miles and the light has stayed off.

Quality design with proper fit to replace one. Install notes!
Definitely recommend if you have to replace your old combined manifold/catalytic converter. A couple notes from my install experience: the 'old' 13mm bolts on the bottom side of the flange were 14mm; the new ones are 11/16" (not 13mm); I needed a M10x1.25x40mm bolt to replace the original bolt on the bracket attached to the manifold / engine block due to the old flange having been threaded but the new one is not - so the old bolt wasn't long enough to add a nut on the bottom side. And notice which side the manifold gasket is facing when you remove and be sure to mount the new one facing the same way. For me the 'trim' around the port holes was 'concave' side 'out' facing away from the engine. But in general the instructions on their site are great. IF you follow them sequentially you will be in good shape. And you might not do something like install the top O2 sensor BEFORE installing the new heat shield, then have to install it again after the installing the shield. But the new pieces fit great; is quiet (found I had a crack in my old 230K mile OEM manifold); and once I replaced the downstream O2 sensor it's like new again!

Good fit where it matters
This part was a perfect match for my 98 Honda Civic LX except for one small detail that I am hoping doesnt affect the car in any way. I installed everything as it was on the 1aauto youtube video and didnt have trouble until i was fitting the bolt that is supposed to go on the engine bracket and bolted into the engine, it seemed as though the whole on the part for that area was crooked or mis-sized to fit the original bolt, with a bit of struggle i was able to put both bolt and the nut on but it failed to stay on there twice possibly because of the engine vibrations but i have yet to try the last method which is putting loctite on there to secure the bolt to the bracket without it unscrewing with the vibrations.

I have a 2000 Civic LX certified LEV and CARB but registered in AZ. Is this the correct catalytic converter (Part #: 1AEEM00796) for my car? Will the other Civic Cat Part #: 1AEMK00182 work as well but with higher emissions, or would there be other performance related issues?
