Currently running a test pipe out of a b16a civic with a skunk2 megapower and OBX header. Next step in my car is to replace header and I was thinking of adding a cat because the new city I'm in requires emissions tests plus my car is just too damn loud. Suggestions, brands for cat? 02 censor hookup? I currently don't have an 02 running to the cat.

 

what year is your car? ill assume its obd1 since you "dont have an o2 running to the cat". in that case really any cat will work. grab a magnaflow hi-flow universal and have a muffler shop weld up some flanges

 

its a 2000 si.

 

well then your car is obd2 and would require a secondary o2. unless you have converted to obd1 your ecu should be getting a CEL for the missing o2.

 

Magnaflow has a great high flow cat for Honda's. Although mine came with the flanges pre-welded so I didn't have to weld it directly to my exhaust system, overall I still pass emissions and works great (doesn't restrict power in my personal experience/opinion)

 

yeah, i guess i should have mentioned its an obd1 setup. i was hoping to find one i could bolt on myself, so @del namco solo magnaflow?

 

yeah, go on ebay and look for the magnaflow catalytic converter, make sure you pay close attention to the sellers % rating, and how many people they have sold to.

its already got it up for honda, just put in your year (on the left side) and then make sure the picture clearly shows thats its bolt on, THEN make sure in the description it says bolt on.
