Default To purchase, or not to purchase?

I'm trying to decide between the coated COBB equal length headers with high flow cat, and the TWE heades and high flow cat. I have done plenty of searches and research, but still have some questions.

Out of these 2 headers/cats, which gives the most power low to mid range?

Right now I have the COBB CAI, and Cat-back. Would it be best to stay with teh COBB headers, or does it matter?

Thank you all.

Steven

go cobb. they're both equal length and the cobb was designed to work with your catback so i'd say, since you're spending a fortune anyway, go with cobb.

i haven't heard anything bad about either of these headers so i don't have anything else to say.

Default Forget headers

I have an 02rs with TWE headers high flow cat and a maganflow muffler. The difference in power is equal turning off your A/C.

Not to be too negitive about this car (which I love), don't waste your money. Save your money and move up to the WXR or STI. Put a on better sounding muffler, better tires, after market brakes pads and a 20mm sway bar and call it a day.
Without huge money, this car will never be "fast". Fun, yes, but not fast.

my $0.02

yea, headers on a n/a car dont do much. not sure how much the n/a headers are but all that for like 5 hp does not seem worth it to me. upgrade your suspension.

headers still give power. and every means to get more power is always good.

hey, post a clip if you can, let us hear your car.

excuse me but to the guy who said that the 2.5 n/a will never be fast....
i have a 98 impreza L with a 2.5 swapped into it. cobb spicy cams,port and polish, unorthodox racing lightweight flywheel (11LB) and crank pulley, borla headers (wasnt sure if i was staying n/a or not) and a 2.5" headersback exhaust..i sure as hell can keep up with a srt4 and wrx. and i have no turbo..maybe you just dont want to spend the money to go fast....

ps. i work for subaru ....unless you wanna spend a lot of money on upgrades on a wrx to go faster.....dont waste your time and money....go with the sti

I agree farrell. N/A's can go very fast. I'm COBB stage 1 now, but with the addition of these headers I am COBB Stage 2, minus the pulley for now. My car is pretty fast. I plan to go full stage 2, plus spicey cams, and lightweight flywheel. pretty much what you have on yours.

Dude,
We are not talking about Borlas here! Both the Cobb and the TWE's will give you more than 10hp...

Crash,
Are you looking at the TWE standard or the HO headers? The HO's will likley give you the best performance of all three, but you must have a minimum of cams and preferably headwork. Without it, you will have a pretty soggy bottom end as they are so big. Only get the HO's if you are sure that you are gonna get the other work down the road and just suck it up with the losses until then. The other advantage with the TWE's is they end in the stock location and you could later change your mind and go RS-T.

Flipside of that, is stock headers would work pretty well with an RS-T, so if you go Cobb, just don't toss your old headers. And I know you already know what my choice was...

And for the guy that said you will never make an RS fast? Maybe an '02 GD body RS like yours. I don't even have headwork or a built bottom end yet, but with 205Chp (dyno proven) and 300lbs lighter than a WRX, I am already at least as quick as a stock WRX. AND, since one can pick up a used 2000 RS for $10,000 and get a built block with all the bolt ons for another $5-7000, one can definitely get to equal or better performance than a WRX with Cobb stage I for equal or less money. But yes, if I had a GD bodied RS, I would sell it an get a used WRX or do what I mention above over building it...

yeah I went with the COBB headers. I do not plan to turbo this car at anytime. I plan to keep her as an N/A project car.
