yo dawg for the money for dat I can announce to all the other carz I be arriven in da lot yo.
Wait, so if intertia while in gear keeps a car running since the throttle plate is closed and all, does that mean exhaust comes out my intake and my intake is actually my exhaust when I'm rolling in reverse with no throttle?
You have hung out your car when its being driven by the wheels to see if there is exhaust coming out the tailpipe! Now thats dangerous!
yes it was at about 95mph on a dyno.
a cat back alone adds no power. a turbo back does. most of the wrx's around my area with exhaust have full exhaust. stock exhaust is restrictive. but im getting us off the all important topic of 99% of members being proven wrong about BOVs. please wagon, go on and tell us how the BOV died for our sins but christians couldnt have a savior made of aluminum so they renamed it "jesus".
BOV is needed to release air pressure otherwise your fart can cannot make the maximum amount of noise necessary to make modding cars 100% illegal.
OH man I love my axleback, it's just the ultimate attention getter.
I love pulling into parking spots at 6K rpm, it's so much better than that show off valve that only made pointless noise for a few seconds here and there.
You know what I do to get attention? I swing the turn wide when parking and crash into the car next to me. That really makes this awesome metallic scraping noise! And best of all its free!!! If anyones around they all look at you, its a cool way to say "hey look at the cool wrx over here". IMO anyways...
honestly i dont think i could live without my wrx having a full exhaust, our engines just sound better then almost anything out there. imo.

"your drive should not be to outdo others,but to outdo yourself"
I don't post a lot .
This is my first turbo car so I am learning.
I'm an "older" guy I guess, and I do like the Psst sound.
Plus I thought it made my car faster
But after reading all this, my BOV is coming off!
Thanks guys for the info!
This whole ''CAR SCENE'' is gay. People who try and look cool with there car is gay. When the BOV blows off no one around you thinks your cool. No matter what you do to a WRX it is still ''Rice''. If its not rice then wtf is it? When ppl say: ''Yo dawg i just got my JDM lip in the mail foo". you cant say thats not rice.
I love cars but i hate the people who drive em.
