    Hey guys... this sound right/legit?

    Just got a 04 WRX (non sti). I think I only want to go to stage one for now but probably stage 2 a little later, and here is my plan... critiques welcome.

    stage 1
    1. cobb accessport and / or invidia g200 catback.

    2. turboxs hybrid 50/50 BOV (from what I read and have heard, this will not harm my car in any way because its not 100% atmospheric) let me know if this is true.

    stage 2 (later on)
    1. catted DP


    also I have researched different exaust sounds and from what I gather, the g200 is medium loud and deep. No raspiness at all. I dont want anything very loud, just something that brings out that boxer engine sound. Let me know if I am wrong.

    critique away!

    welcome to the club!

    i would not steer from cobbs map notes & what parts are compatible.

    stage 1 map is not made for anything else except a stock car or a car with a catback. no mention of a BOV anywhere

    edit: if you want a whoooosh sound you can do an intake silencer delete. free mod. easy to do. doesnt harm anything

    I know the bov doesnt have anything to do with stage one or really even stage 2. I just added that under stage 1 cause I wanted a bov. I dont want it to be too loud like most, but I still like the sound. I was told that the hybrid bov was basically like running the stock one except it blew off a little air to atmosphere just to get a little bit of that sound that I like. Why stay away from cobb?

    That was not the response. Do not deviate from Cobb's map notes.

    Do not use "and/or" between the AP and the catback. You will need either the AP or some other means of mapping. You could consider an up pipe and definitely drop the cat back.

    im not sure i completely understand what was just said. Basically I just want to add 30-40 more hp, have a nice (not too loud but deep) sounding car with a hybrid bov. You said dont get catback and get uppipe? I will still have stock exaust. I talked to a guy from rally sport direct and he said running a catback was still stock according to cobb so basically it would just be for sound and the AP would give me the extra hp with stage 1, and later I could add a dp and use the ap to go to stage 2.

    OK. You initially stated you wanted to add a Cobb AP and/or a catback. You must add a Cobb AP or some other means of management if you are to modify the exhaust in a manner meaningful enough to increase output. Whether you add a catback or not is irrelevant, it will only affect noise, not output, and not management needs. Therefore you cannot use "and/or" in that statement.

    Basically I just want to add 30-40 more hp,
    "Just" sells your goal short, as you are really asking to substantially increase output. You can do this but you ought to follow specific steps. For your model the first step should probably be an up pipe, as the stock unit has a cat in it. Replacing this will make your car illegal on any public street in the United States, and so will removing the cat in the down pipe later.

    have a nice (not too loud but deep) sounding car
    The deep sound can be generated with a catback but that will not increase output. To increase output, you will need a management system, an up pipe, and/or a down pipe. Cobb make a management system, the AP; there are others. If you are going to use Cobb's management system you must follow their map notes, meaning you must install only parts specified in those map notes. This last point was the gist of the response you got -- you were not told to shy away from Cobb (although you probably should have been, since they are not cheap; however, for a new user they do provide convenience and a certain level of safety and it's usually a case of "if you have to ask, use Cobb" IMO).

    with a hybrid bov.
    At best this will make noise. At worst it will be a pain. I'd save my money but it's up to you.

    You said dont get catback and get uppipe?
    I said you could consider an up pipe and you could drop the cat back.

    I will still have stock exaust.
    No. You will have modified the up pipe. This isn't specifically required by Cobb I don't think (I am not a big fan of their stuff -- I like money more -- but I don't think they spec it for their "stage 1."). If they require it and you use their AP, you have to install what they say their map covers; if they don't require it it's still not a bad idea at all to get rid of the cat in the up pipe before increasing boost according to many people.

    what i do know about cobb ap is the requirements for stage one and 2. For stage 1 I dont need anything at all, I just plug in the ap and flash stage 1. I can also have a cbe for stage 1 cause this is still considered stock to cobb. To go to stage 2, i have to have a dp. So basically Cobb is saying for stage 1 I can have a cbe or nothing at all to flash. For stage 2, the only thing I "have" to have is a dp, but a tbe can also be part of stage 2. This is what i understand of it anyways...

    You should also have an Up-Pipe for stage 2

    an UP is the best way to increase hp for the money compared to any CBE, and with the UP it is still stage 1, im kinda in the same boat as you, i want that deep boxer sound but i went with what will get me the most power for the less amount of money and later on i will get a DP and CBE

    and welcome

    ^an aftermarket UP doesnt really increase power a whole lot. it will free up a little bit of HP [your butt dyno might be telling you otherwise ]. if you're @ stage 1, it's probably the stage 1 map where you feel the difference in power; not necessarily the UP. 99% of the time, it's just done so the cat from the stock one doesnt grenade into your turbo

    How hard is it to change out the up/downpipe on a 04 wrx? Does it take 2 people or does a specialist need to do it?
    thanks
    oh.. and would a dp mess with the emmisions test and/or would it trigger check engine light?

    Not too difficult. Two people makes it easier.

    Catalytic converters are emission control devices, and you are removing them. Depending on your areas emission testing, it could pose a problem. CELs are taken care of via tuning (e.g., Cobb AP).

    I don't have much to add to anything everyones said, but I suppose I'll add a lil about the BOV: Whether it's 50/50 or not, it's still a BOV. Think about it. Just because half the air is being released into the atmosphere instead of all of it, doesn't really mean anything. The problem with BOV's is that the Mass air flow sensor has already read how much air is incoming to the engine, told the computer how much, and the computer has then measured out the correct amount of fuel for that amount of air. Now, if half that air is released to the atmosphere (which it is)...needless to say, the air/fuel ratio is now skewed. the blow off valve is post-MAF, and so the computer has no way of knowing that the air is no longer there. It wouldn't even matter if you got it tuned, because, again- it's post MAF. If you get it tuned the computer knows how much air it needs to draw in blah blah blah. It still doesn't know where all that air is going every time the BOV opens. See the issue? It may, being 50/50, be less damaging than a full blown BOV, but think about it. You are forcing a lot of air and fuel into a small space, and igniting it. This must happen under fairly good conditions to not have problems, the mother of all of which is knock. Do you want to deal with the problems knock can cause? Such as thrown rods, spun bearings, etc? I certainly don't. Cobb Stage 1, is, to my knowledge, for COMPLETELY stock cars. This means all that stage one map on the AP is doing, is telling the computer to work better than the stock tune told it to. Stage two is usually uppipe, downpipe, and TBE, plus the tune. Air intakes just mess with WRX's, forget them if you ever thought about it. the cat in your up pipe will eventually rot out and sent bits of cat into your turbo. This is bad, obviously. But with just an up pipe and a tune, you can get much better driveability, much better power, torque, you name it. And the up pipe removes of the possibility of something causing your turbo to go boom. Now you just gotta worry about the turbo itself making the turbo go boom- which shouldn't happen, unless its been beat on or overboosted.

    Also, you may think you want more extra power than you actually do. Getting rid of the stock tune will probably increase your power band fairly drastically, give power where there was none before, and more hwere there was some. just remember: The numbers that people throw around, like horsepower and torque, and very circumstantial, and essentially useless in ANY comparison. Say wrx A has 400 horsepower, and wrx B has 400 horsepower. What mods? Where in the RPMs is the power present? For how long? At the wheels, or at the crank? gear ratios? Weight? Were they tuned on the same dyno? Was the humidity, air pressure, and temperature the same for each car on the dyno? were they done consecutively? What altitude? a 10 second car at sea level might only be a 12 second car at 3000 ft. There's so much that goes into how a car feels when it drives. The stock tune on these cars is pretty much a sissy tune. You'd be astonished at what a simple tune can do for you.

    Tell me if I'm wrong but the 04 wrx boost max is around 13/14. With a stage 1 tune the boost can reach as high as 16 psi. Is this a big enough increase to use a hybrid bov? I thought after market bov's were used for higher than stock boost? If it will likely cause problems, I'll just go without, but I like the sound. Also... if I were to go to stage 2 "cobb", I'm guessing the boost may reach as high as 18 psi? If this is so, a bov could be used right?
    thanks for the help
