    Hi I have a simple question about my WRX

    I am recently a new owner of a 2002 Subaru Wrx. I have been noticing that when i take hard turns around bends there is a slight humming noise. I was hoping someone would be able to tell me possible causes for this noise.

    I was also wondering, what mods have people been mainly putting into this beast? Any suggestions, my car right now is stock but I'm a guy also looking for better performance

    I would greatly appreciate any comments and thank you

    the most effective first mods are catless uppipe and turbo back exhaust and engine management like the cobb accessport.

    that will get you lots more power without reducing reliability.

    As a newbie that has done a buttload of reading recently, you need to ask yourself a couple important questions. In lamest of laymans language...

    How much are you willing to "invest" ? LOL
    Are you in a state where emissions are not too strict?
    Do you want it or care if it's loud/quiet?
    Fun car or everyday car?

    I am on a fairly tight budget, I want my car(bone stock 2003 WRX) to stay pretty quiet, but I want a few more horses and keep it reliable for everyday travel. New York State.
    After advice from a couple vets here and some hours(and hours) of reading, my best bet is to EM(engine management, tuning/changing stock computer stats for better performance) first. This can increase overall performance(20-30hp Cobb claims) WITHOUT any engine part mods. Maybe just airbox or filter improvement. Looking at about $800 for EM and K&N filter, $900-1,000 with improved airbox.
    Catless uppipe and turbo-back exhaust will be more in the $1500-$2000 range, but you MUST have EM ($700+-) to use these, so plan on close to $3000 IF you do all the work yourself. My numbers are generous(expensive), mostly for higher quality/brand parts.
    If you are lucky or have connections, you might be able to find someone to tune it for you without purchasing the EM package yourself, a HUGE savings. But I think I would like to have my own because it comes with multiple settings like valet(so if you have someone valet park your car, the boost and all are "dumbed down" so they cant go blasting in your car) and settings for different octanes, god forbid you cant find 93.
    I want my car to remain a "sleeper" and NY emissions are stricter now, so I will keep a cat somewhere in my exhaust, probably after turbo.
    There are ways to "gut" your uppipe for free'er breathing, you can find instructions somewhere on the site here, instead of buying another.
    Do yourself a favor, do a bunch of reading on the site. Most of your questions will be answered before you ask them.

    Some states (NY included) require a visual inspection - others do not. Check your local ordinances.

    The Cobb AP is by far the most popular choice. You can also look into open-source tuning. For this, you'd need a tactrix cable (<$100) and a laptop - if you know where to look, you could probably find a local Subaru owner who would be willing to help you out to save you from buying the tactrix. You can get a StageII XPT map (open-source) for approximately $75, I believe. This would cut down seriously on your costs.

    If I were you, I'd peruse through the for sale threads on here/Nasioc. You can find some pretty good deals on getting used exhaust parts. 2.0L engines don't have an issue with boost creep, so you can save some $$ (again, check your local ordinances about a visual inspection - if they don't require it, then it's just an OBDII check, and as long as you don't throw a CEL, you'll probably pass).

    You may want to look into the TurboXS Stealthback exhaust. This will mate up to the stock muffler, which will help avoid any "modified exhaust" tickets. When I get the cash, that's probably the route I'm going to go.

    I would advise against gutting the UP, personally. If you want to save some money by gutting, do it in the DP. The last thing you want is for you to have pieces of platinum get sucked into the turbo. Spend the money and just buy an aftermarket UP.

    Yikes! Sorry for making that mistake. DP is what I should've said

    No problem.

    I notice you're from Orange County. I know people on Nasioc have a Hudson Valley meet every Friday. You may want to take a look at that thread, and if it's not too far from you, you should attend. It'd be a good place to meet some local Subaru owners.

    Very cool. Where in NY you at?
    I will check it out.
    Thanx again.

    I believe the noise is coming from the tirods? The noise only comes when im doing sharp turns with my car. I'm only asking because i would rather have it get looked at properly before it gets worse.

    OK slide under the car and look for obvious problems with the steering and shafts. Remove the plastic splash shield if need be and/or safely lift and support the car to check. When lifted, see if there is any play anywhere.

    Also -- see if either tyre rubs by checking for tread wear and/or marks on the fender lining from hitting rubber.

    I just bought a 2002 WRX wagon that makes a slight scraping noise when I turn left hard and hit the gas through the turn. It sounds like tire scraping wheel well, but I'm not sure.

    Is it possible that the rear diff makes noises? This noise always sounds like it's coming from the passenger rear corner.

    I know this doesn't help exactly, but I have the same car making a similar noise.

    2002 WRX wagon, 69K miles. At first I thought the noise was something rattling around but I'm almost positive it's coming from the rear outside the car.
