Wussup Fellas, Im tryin to purchase a high flow cat soon and was wondering what to get. Im not tryin to spend a crasy *** price just for a cat. may be around 250ish. but i herd carsound cats are good. Have any of you guys used or heard about obx cats? its pretty cheap and i seen ppl used it but nvr commented about it.

Random Technologies makes high flow cats for specific models that are a bolt on affair and cost around $150. I have one on my 99 si...

PphamEK

yea, man i seen them, how u like it? U feel a diff?

tercel95

I got the cat and the exhaust at the same time so it is hard for me to tell for sure. I'm sure they are good for a few hp though. I can vouch for the fact that the installation was very easy...

I had a magnaflow cat on my old car but that was a custom job. For some reason that high-flow cat made the car sound amazing, something I haven't been able to replicate since. However, after about 6 months the magnaflow cat imploded and I had to replace it...

PphamEK

ic how long have you had that cat on so far?

tercel95

I've had the random technologies cat on for about 50,000 miles...

PphamEK

Catco cats are pretty good and affordable also.

PphamEK

magna flow is direct fit? i though u would have to weild flanges to it?

PphamEK

yea man i was thinkin of catco too, but im lookin for an exhaust where it already has flanges so i can just put it on

tercel95

What kind of setup are you running? You want to make sure you get a cat that will match the diameter of your exhaust...

I have a 94 civic hatch with a gsr swap, apexi header, apexi n1 catback, aem cai, about it for engine performance wise.

Check the link, the linked one is a direct fit. Although they sell a non-direct fit also that needs welded. Ive heard good things about the Magnaflow, and am getting one installed in a couple of weeks myself.

Again I had a magnaflow custom cat on my old car (2.25" through) and was really happy with the performance and the sound. The only reason I recommended the RT Cat was because my magnaflow imploded on me with < 10,000 miles on it...

Gut the stock cat. Cheaper and same results in power, maybe a lil noisier though

jordanhxc

*cough* gut your cat...it'll be very high flow haha

tercel95

Not true you can lose power with a gutted cat, plus they aren't as wide as an aftermarket one...

I've been using this for the last year or so. My OEM died, threw P0420 and I had nothing else to do. I opted for Magnaflow, but the exhaust shop has had a lot of people come back with Hondas because of the placement of o2 sensor on universal weld-ins, so I just got a Catco for same price.
Rattling went away, old cat must have been quite dead.

Careful with your cats guys. BAR is really **** when it comes to those now that the new law passed in January. The cat you have MUST be a special CARB approved one with some E.O. numbers on it. All the universal cats that auto zone or kragen sold at one point are completely useless. I failed my first BAR appointment because they couldn't prove my cat was for a 94-95 LS. So I had to go out and buy a brand new one. Then I passed perfectly. New cats are awesome. My smog numbers were wayyyy below average.

Just a heads up that the new law for California people SUCKS.

The dude is from MD, MD is very lax... If you are OBD1 they hook you up to a sniffer, if you are OBD2 they plug a scanner into your OBD port. If there are no CEL's than you pass. There are even ways around it... And that is only if you live in a county with emissions which luckily I do not...

MD is the 5th worst state for personal freedom, right under Cali, but at least they don't chase after car enthusiasts with a money making agenda...

If I lived in Cali I wouldn't even bother owning one of these cars...

The ones in the links are direct fit, with the flanges and everything already on and it's ready to be bolted on. I have the OBD1 version (first link) on my car, and I love it.

Magnaflow also makes universal cats, which are the ones most people are used to seeing/hearing about.

sauceja

Yeah gut your cat so you can have a raspy sound. Thats the only reason I put one back on is to have a mellow smooth tone throughout powerband.

Like a 2 hp loss is worth not running a cat.

PphamEK

my car is a obd1, so the o2 senser should be at the header and not at the cat right? cuz i got the header with the flange cut off and theres no o2 senser hole on the header... So they all come in 2.25 for the magna flow? and i would have to get it for the integra?

thumper64

No idea what you're talking about....
My header on my hatch doesn't have a hole for an O2 sensor, the test pipe does though.
I say to find a stock cat, swap it in for emission testing and put a test pipe in the rest of the time if you can.
