need help on cat converter

search feature sucks, i type in high flow cat and get the photoshop threads and ****, nothing that pertains to what I am looking for.

I am looking to get a new exhaust soon, and I am pretty sure my cat is about to die on me.

I would like to get a high flow cat instead of a test pipe because i don't want to throw a CEL.

I can't find anything that seems reasonable, the Random Tech High Flow is almost 300$. I can buy a whole cat-back for that price.

What and where should I get a decent high flow cat?

Re: need help on cat converter

well just to give you a heads up... you can run a test pipe as long as you extend the secondary 02 bung. you can use a spark plug defouler. you screw the defouler in then then secondary 02. the cost of the part is 6.00- and i promise you wont throw a CEL>

Re: need help on cat converter

And a lot of the high flow cats will throw a code as well. But if you need one, I used the magnaflow one, and I have had no troubles at all!

Re: need help on cat converter

cut the old one out!! haha, thats what i did b/c i was broke.
no really, dont do that. i only did it because i was bout to get a whole new exaust, and my cat was busted up, makin rattlin noises. but a magnaflow cat is the best ive heard of for a decent price. u can actually get a true fit one at autozone for like 200.

Re: need help on cat converter

does your state check for smog output when they do your inspection? if not my friend had a mazda mx3 and he bought a "high flow" cat off of ebay. it turned out to be a glass pack lol. but it resemblles a cat so he had it put on inplace if the cat. it sounded awesome and your could tell a difference in power best part is it was only 20 bucks.

Re: need help on cat converter

yeh, my state does emissions testing, but i got mine this month. and right after that the cat went out. i only cut it out because i know im replacing my enitre exhaust soon. but yeh, you can def get more power without the cat. it sounds a lil better too.

Re: need help on cat converter

yeh you could do that too. a peace of rebar will work, or just a hard metal pole. i just didnt feel like dealing with the bolts, they are so damn hard to deal with, so i just cut it out and welded a pipe on. its the same concept, i just think its easier.... depends on how long it has been since you changed your cat and how hard it is to get the bolts off.

Re: need help on cat converter

I love all these people that remove the cat and claim to have felt the hp increase. We stood at the dyno one day and tested a car back to back, running no cat made a best of 0.5hp increase over a high flow, which made 1hp over an (albeit new) OEM one.

All dyno runs were on a DynoDynamics dynamometer running in Shootout Mode (in essence, DD claim that a car run in shootout mode will get within 5% power figures on any dyno in the country) within about a half hour of each other. The car was a Ford Focus with the NA 2.0L Zetec 4 cylinder that other than an intake, header, exhaust and mild tune was stock.

How do you "extend" the secondary 02 bung?

I live in Kansas and they don't have emissions nor do they really care how loud your car is.

Re: need help on cat converter

I don't wanna sound like a tree hugger or anything, but why are people on here supporting test pipes and not using cats...? If this forum is so against bad things (street racing, blah blah blah) then why are people promoting cutting out a very necessary part out of their cars just to get a fraction of a hp?

I guess I don't really have any room to talk; I'm a technician in a 1500 MW power station...

Yes, all extra 0.5hp!

I agree 100% Jesse! The thing of it is that most people don't realise that the exhaust system needs to be designed like the fluid dynamic system that it is. The cat converter is only a restriction if it's not the right one for the application. Like any fluid dynamic system the restriction is not so much the innards of the cat (called the "biscuit" for reasons unknown) but the sharp reduction in pipework size. Fix this and there will be next to no restriction.

Bingo was his namo. Exactly the same concept on our new Selective Catalyst Reduction system, like one big Cat.

SO2 is bad.

try that with a clogged cat and a test pipe and check out the difference.
thats the only reason i cut mine out. i didnt have the money for a new cat.

not tryin to be a dick or anything, im just sayin that im not promoting takin out your brand new cat just to get more hp, i just thinks its better to have no cat then a busted up one
