Default New guy with a few questions.

Hi everyone, I'm looking go get a 03 WRX, I have been on the forum and looking around and I am very impressed by this place! I see everyone helping out each other, and lots of Info. I'm on BMWPlanet.com, I currently own a 1978 BMW 320i, I blow the motor so we are making it into a clud racer, and I need a new car. I have a few questions.
1. I know all about the break-in and was wondering would it be really that bad if I got exhaust and a BOV?
2 which exhaust is louder in order, the STI axle back, HKS ca/ti cat-back, or the Apex'i N1 cat-back?

Thanx for all your help. I am looking forward to maybe seeing some of you at some meets.

P.S I live in So Cali, in Newbury Park/ Thousand Oaks.

BOV should be no problem before break in, from what I know, but just to be safe I'd wait til 1000 til I put on an exhaust. If you want loud you might want to look at a cat back, my friend has a Blitz NUR Spec, got a fix it ticket........any way good luck with your car, enjoy

Hey scoobyRex well i am new here also but i know it doesn't hurt to change the BOV before break in. I had a 97 eclipse GSX and i asked the same qeustion and everyone told me it wouldn't be a problem. As for the exhaust i am not sure if you have to wait on that or not i know from subaru you can get the sti cat back exhaust right from factory so i don't know how that would work what i would do is if you don't want to wait and you want it on go and put it on just drive it carefull and you should be ok.

I don't know I think that you should give it sometime before installng anything on the car. Because if anything breaks on the car and you bring it back they would say that the aftermarket part that you but on the car cause it and they will not warnnty that.

Just my 2cents

aftermarket upgrades and risk are subjective to how conservative you are. My ideology is on the conservative side and would suggest waiting till break in. In reality how would less backpressure in your system create a problem when the car is new or Broke in is probably the same. You live in a great area as the SCIC has alot of members there. Id ask on your local forum board because much of MOD'n Subies and risk is dependent on the dealerships attitude and policies on them ... seems that some dealers sell WRX"S with extra aftermarket goodies. While others pitch a fit if you have a different exaust system. Again this is dependent upon YOU. Some guys are scared poopless when they read of a dealer denying repairs.
play it safe,,,,,,,,,,,,,,,or not>?

p.s. check the factory forced forum for exaust info but I think that the hks is the loudest.

Hey guys that alot for your thoughts! I think I will wait till I hit the 1k mark then go to my dads shop and put everything in, About the exhaust, I have heard the HKS, and I like it but I dont think I want to pay $750 for it, I like the apex'i look but have not heard it yet, and my friend has the STI and its not that loud, I Was wondering if it is louder then the STI. again THANX!

Another reason to wait until after break-in: If a manufacturing defect is going to show up, it'll most likely be in the first few thousand miles. I wouldn't put anything after-market on the car until the stock equipment had proven itself reliable by going 10,000 miles or so... (Or am I just superstitious?)

Default worried about sound

If you're worried about the sound for exhaust check out the GReddy EVO, just about stock quiet. Check out the latest issue of Turbo Magazine, there is a 12 exhaust WRX shootout, Greddy was one of the quietest, gite it a look. It gets a little louder when you remove the resonator chamber in the fender but that's no big deal.

I dont really want a loud exhaust, I heard the HKS CA/Ti and the sti axel back, I was wondering where the Apexi is compared to those 2.

What is boost spike? Here goes.... when you take off and wind up a gear, you're obviously winding up the turbo too and building boost. But when you shift, you take your foot off the gas and the throttle plate closes. The turbo is still pushing boost, but runs into the wall that is the throttle plate. So the air bounces back to the turbo and disrupts its spinning the turbo doesn't like that. Thats why you get a blowoff valve, it releases that excess pressure so the turbo can keep spinning un-disturbed.

I thought a boost spike was a condition of temporarily high boost? Like you're running 15 pounds, but then it spikes to 17 for a second...

Yes that is a boost spike.

If the turbine spun the other way because of a 'block' then buh-bye turbo. Also I've never heard of a "throttle gate" Do you mean waste gate?

The stock BOV is fine if your using the stock turbo also. The only reason for an aftermarket BOV is if you have upgraded your turbo and/or are just itchen for the 'sound'.

He said "throttle plate." You've probably got one, it's a performance part
