already can answer that question, yep they do make one and you can get it off of ebay. It hooks to your exhaust tip and is suppose to give that sound. Now if it really works is another thing but I will stick with my evo2 lol.
no, ownage would be when someone heard it, then discovered its fake by either listening to the engine, or destroying you in a race. and the ownage would be on you.
hhahaha they actually do...i read it on turbo or import tuner...its like the alarm speaker things...it hooks up to ur rpm guage shiet and every time u hit a certain rpm it would make the noise...no joke...its in the back of the magazine where all the adds are at....
look at VIS it is called a turbo effect kit it comes with a speeker and it "blows off " at what ever rpm you want, only problem you have to be the worlds best shifter to make it convincing... and shift there every time
as much as i love the sound of blow off valves....those things are ghey and i could think of a whole bunch of things that i could do with that 150 bucks
oh damn! i just noticed that lame site had a sound sample. listen to it! it sounds like some shitty cheap ass bottle rocket! all it needs is a loud bang at the end
i just got done hit turbo on my work pc.... lol everybody was like wtf is that.. i told them i put a turbo on it....lmao.... i want one for my skateboard...lol
