best cat converter for my 00 civic

[prodigyusmc]

i just bought this civic and it has test pipes and i need to install a cat converter within a year so i can pass state inspection. should i go with a hollowed out cat converter or just get a high flow cat converter. around how much hp will i lose by putting a cat converter on. thanx for any input

What do you think a hollowed-out cat is? If you knock the guts out of a cat converter it won't serve any emissions purposes anymore; hence, it basically becomes a test pipe. If you need to pass an emissions test then you'll need a cat converter with the guts intact...

you don't have enough power to notice a loss from a cat being installed. just get whatever you can thrown on for the cheapest amount of money.

i guess bro, sorry man i been short tempered since i got back stateside

im not to happy that i found out that i have to jump thru hops to get the stock injector on for inspection cause the previous owner put low impedence injectors with resistors, so either i switch it to high impedence injector and get rid of the resistors or i have to play mister electric every year to pass state inspection

That's all right - I had a day at work myself today - it sucked pretty good.




Emissions eh? Have a look here: https://hondaswap.com/members-lounge/e-vs-emissions-501184/

very helpful link, the guy at the shop here told me that after i get the cat converter put in that all i would have to do is put the stock injectors and ecu and i should pass emissions, im not even gonna act like i know alot of stuff here, cause my previous car was a mustang so im not sure how accurate this info is.

 

[Dual-500]

There are a few around here that know stuff. That link is a dandy for emissions - if you need to refer to it.

Stock injectors? So a ECU change too? If the motor is in decent condition, you should be able to get it to pass without too much hassle. And these guys can probably help a lot - many have experience with boosted engines.

Good luck with it. Mine, I just have to put the cat on I think. The cycle will be the first emissions test with the new engine I just put in my '91 hatchback.

Who knows what fun may lie ahead. Got to clear a CEL for the TPS first.

let me kno how that goes for u.

 

[Dual-500]

Ok - I'll probably post the results on the emissions thread.
