So its about time i upgrade my headers and cat and i have one simple question? I looked around and i found a direct fit magnaflow cat for a great price.

Are these even comparable to the R/T cat as in performance gains? Ive searched google and every1 says oh yea its a good cat but havent none of them said anything about performance[scratch] .

I realise with the r/t i know what im gettin but to spend 350 bucks on a hfc that alot of people had problems with, i dont really feel like buyin it, id raither go turbo then.

Thanks for any help

i believe they are comparable. I've had my rt cat for two years without any probs. Actually if i could go back i'd have a friend just make me a orp. Save 300+ bucks

The hfc will rob a negligible amount of power from the car with a good header.

If I were in your shoes I would go with an SVT header and a modified R/T cat to bolt up to a Zetec flex. That will make the most power for you. A Short header and a cat in an L pipe will be more restrictive.

i like your idea dan but i dont think i could handle the svt header install... I like the fact that i can just unbolt the header and cat and just replace em with jba or FR header, either 1 i can get for good prices. And the direct fit cat i can get for 200. Max is 400 and thats about how much an svt header kit costs ( i think). I just wish i could get the gains that the long tube offers.

for your situation the svt header and rt cat is the best bet and if you want you can have a test pipe made as well for when you are racing and bolt the cat up for emissions day

I think the SVT header kit and modified hfc will run you about 600 total. And I'm pretty sure either way it will be a pain in the you know what each time you replace the header. But good luck to you.

^^ that i can agree with, im not lookin forward for swappin out headers weither i change my mind or not. Im also not a racer, i just want more giddy up and go, a sick ass sounding exhaust, and to clean up my engine bay. I will be wrappin the headers and sprayin silicone over it...

So it leaves me to this, any1 say itd be worth the money to buy a magnaflow cat or not. If not i might try the long tube route but thats for another day to think about.

svt header is the best to do.. It's not diff at all to remove the manifold.

i have the r/t hi flo (which is rattling now...i did buy it with over 20k and have put 30k on it...so its to be expected) and i must say is did up the tq and hp in the mid range. my dyno is in the zetec dyno thread, take a look. For as minimal of mods as I have, some with more are only making 5-10hp more than me for spending a bunch more, including headers (whether SVT or long tube....)
