    Welcome and happy modding
    Ok yes thank you, I am still learning all that. And that's what I ment then was a BPV. Is it worth putting a better one on?

    On that side note though I have a 2012 R1 that I have been slowly trying to get built up. How about yourself, what do you have?
    OOoooo nice! Post some pictures of it in the sportbike thread! http://www.clubwrx.net/forums/motorc...er-thread.html

    I have a 2003 r6.

    And the BPV is a good upgrade once you get above certain power levels. At stock levels it is fine though.

    My understanding is that the stock BPV is fine up to stage 2 levels, but past that you would want to look I to something a little better. I have a different stock BPV on my car (sti) so I am not 100% certain, but past stage 2 I know most wrx owners replace the BPV with something better quality like a forge or turbosmart. Long story short it is not a priority unless you have a failure of some kind with your stock one.

    Btw the r1 is sick!

    Check your local craigslist, thats where I found my Accessport and SPT exhaust at. Much cheaper than brand new. The SPT exhaust isn't the best as everyone else has stated but if you can get a really good deal on a used one its worth it. Got mine for $150 off of a 2010 STI. Accessport was $200 and some Ar-15 parts. Some people get fixated on new exhaust because they are shiny and clean but other than the tips look at any exhaust after a few thousand miles not so shiny anymore. Point being, if you can get a good deal on a used exhaust do it.

    The WRX BPVs are plastic and have been known to asplode with as little as 17-18psi...so anything more than that, you're looking at potential issues. Same goes with the plastic endtanks on the stock TMIC. Both of those are actually good upgradeable items at Stage 2.

    If you're going to upgrade your TMIC, process west makes some pretty slick looking TMIC... that's what I'm targeting for upgrades.... way down the line... :P

    Also, I got my epeen totally demolished the other day... I opened my hood next to an STI and noticed how much smaller my TMIC was..

    First, welcome! Grats on new rex! As was mentioned, start with the basics. The stock air box is good past 300WHP (close to 400 at the crank). I know because I run the stock airbox on a 300+ 2011 WRX. I also run the stock cat back exhaust. Your first bottle necks will be: downpipe, fuel system, boost controller/bpv and intercooler. As was also mentioned, the stock TMIC is a joke. I went with the Process West TMIC and love it. I gather this is your first WRX. Take it slow. I recommend buying the Cobb AP and starting with a modest stage 1 OTS map which requires no hardware. There is actually a slight power loss with stage 1 (I have the dynos to prove it!) but the area under the curve is increased, and the band is much smoother. Once you decide what you want from your subie, go from there. Personally, I think the stock suspension is inadequate even for the stock power levels, but then again I enjoy turning fast more than top speeds. Again, most ppl will tell you to get an intake and exhaust...which is great if all you want is for your car to sound cool. I would avoid the SPT exhaust. At $800 I would rather go with the Invidia Q300 ($900 on rallysportdirect.com). There are many threads that clear up good first mods and the shortfalls of each generation of wrx. keep us posted and good luck!
