  • its a y pipe. you open that valve. to make your car sound louder(open headers) and close it for driving (performance)

  • so whats the point of this? performance?

  • @spriteremix02 Sleeper status thats why. U have this thing on an ok to decent sounding exhaust, then you open up the valve & off you go =D

  • @spriteremix02 to control sound

  • @spriteremix02 Nope, it just makes it so that you hear the actual sound of the engine isntead of the usual sound coming from the exhaust pipe which is obviously not as cool ;)

  • @spriteremix02 if the engine is N/A, it won't bring much performance, but if you got a turbo or compressor engine that the lower restrictions brings you big power gains...
