Aftermarket Catalytic Converter for 1999 Civic EX

hsimpson · 09-20-2009

I am looking for recommendations for bolt-on aftermarket catalytic converters for my 1999 Civic EX (has the cat under the car, not on the manifold).

I don't want to waste $530 for the OEM unit (that is discounted), but when I bought one brand for my other car, it was a real pain because it did not line up correctly and the 02 sensor opening was in the wrong place. Not worried about the CARB baloney...

My main goal here is a durability right now because I am keeping the car stock for now.

Thanks in advance

Thanks for the advice -- they seem to have a lot of good info on their site. Only thing I need to confirm is fit with the 02 sensor placement. They put theirs in the rear and mine is in the middle. Probably not an issue.

you can always get an O2 sensor extender if it doesn't reach
