Hey guy's whats going on. I have a 2004 Cavy LS 4 door and i am looking to do huge stuff to my car this summer due to me actually having a job and money to support doing stuff to my car. I am wondering what would be the best products to get as far as an intake, headers, and exhaust to get.. My buddy just got an exhaust made for him at a shop so i think i might get that in dual but if there is anyone with better ideas for exhaust as well as the intake and headers, please let me know what the best thing for each. I would also like to know where i could get a high flow cat, i looked on rksport and it says that the one that i would like to get will not fit my ECO so idk. But if someone could please help me i would very much appreciate it. thanks. also, i am sorry if this is a repost i am just trying to pull this all together.
there is no such thing as best either.
start off by reading the FAQ
there may not be a best but there is certainly parts that are crap and dont work as good as others

Like stated above, I don't know about the best, but I would recommend an AEM Cold Air Intake.
As far as a header I think your choices are:
Pacesetter.... Cheapest and I haven't heard anything negative 4-1
RK Sport....I think some people had fitment issues with these 4-2-1
Weapon R....Same design as RK's, but fits better4-2-1
DC Sports...Most expensive not too many poeple have these yet, cuz they just came out.
(And I heard, not sure, that the DC header doesn't even come with a downpipe.) ^4-2-1
I am getting my high flow cat from Gravana Tuning. and Yes the magneflow hi-flow cat fits.
If you search around you will find ALOT of information.
I hope that helps a bit.

^^^^ the weapon R is 4-1 not 4-2-1
Weapon-R ECOTEC Header is 4-1? Wow, I thought it was 4-2-1. I must've heard incorrectly then.

You heard correctly, it does not come with a down pipe.
Here's how it works. Don't listen to anyone on this site unless they actually have the parts/have done the work. Very few people know what they're talking about and they all think they do. As you can see you have everyone thinking something and the opposite is true.
Take for example me doing an 03 conversion on my 97 cavalier. I had alot of people tell me most of the parts would bolt right up. No. The only things that bolted up without modification were the hood hinges and the headlight housings. Everything else I had to modify. And you can't say they were crap aftermarket parts because they were all off of 03 cavaliers.
Moral of the story. Go to the company's websites and check out the info for yourself. And from that information, you decide what is best for what you want. Only then will you know for sure.
Good luck with all your modding.

I found a picture of the Weapon-R Header for the ECOTEC and it looks like it is a 4-2-1 to me, heres the picture:
Anyways, before this thread gets jacked or anything, like everyone else has said, every part has its up's and down's so just do your research before you go buy something.
it is , i have it, the pacesetter is a 4-1
Intake - Weapon R or RK sport, or get the RSM TB and intake combo, cold air is a gimmick and the aem is 50 bucks more
Header - Pacesetter or Weapon R the rest are overpriced and wont do any better
Crank Pulley - Light and still not underdrive the RSM Racing
Upper Mount - The RK sport is a beast
Lower Mount - RK or RSM not much difference here
Flywheels - spec or fidanza , RK is crap
Throttle Body - To my knowledge RSM is the only one out there with it
Heads - Patriot or RSM both are good flowing
High Flow Cats - Magnaflow pretty much anything else is crap

hmmm thats wierd...Weapon R's site had them all listed as 4-1....oh well
anyways... i have the rksport 4-2-1 and ill be putting it on next week...ill let ya know how i like it
I have an OBX header on my car, same design as the pasesetter. Installation was difficult because my OEM downpipe wouldnt unbolt. I am very happy with the performance increase. I used a magnaflow high flow cat with it as well. Very pleased with the mid to high rpm gain
thank you everyone for your imput and for the help.. i am for sure giong to be using all this information to make one of the fastest 4 door cavy's in the us haha. thanks again everyone for your imput and if u find out anymore please let me know
if i were you i would save up your money go for a turbo kit or a supercharger kit. RSM makes a great supercharger kit from what i heard and hahn makes a good turbo kit. your lookin to make the fastest 4 door you said then go forced induction.

here is what i have
Intake: Injen it is a Warm Air. and like Rodimus said the cold air intakes are a gimmick. people see "Cold Air" and automatically thinks its better. in theroy it is but in reality its not.
Header: pacesetter ceramic coated
cat: carsound cat made by magnaflow
engine mounts: the ones from carcustoms. they are all the same.
exhaust: Thermal exhaust system. its overpriced it was an impluse buy at the time. but im happy with it pretty much
far as your TB goes, you can have your stock one bored out for a lot cheaper than what you would pay on any othersite

so far my buddy adam coleman ( the kid with the sweet azz red sunfire on here) is gonna get me a weapon r secret weapon intake, and i think im gonna go with the pacesetter headers cuz everyone is saying thats the way to go, i think im gonna get a custom like 21/2" exhaust piping with that magnaflow cat adn some straight through tips. my buddy got a single exhaust from the shop and ill just get the tips he has cuz the sound is throaty and i like it... also if anybody has some good links for me to check out for parts please post them on here as well

ok im kinda stuck between an intake, should i get the secret weapon or just the dragon... ive read reviews on some sites and i hear both are good but the secret weapon is way more expensive
neither, get one that connects directly to the TB.
If you're gonna make one of the fastest sedans you're gonna need boost. If you're gonna boost you need bigger than 2.5" exhaust. If you're gonna boost don't bother gettin the intake either. Just some things to think about.
