  • All I can do is laugh........

  • @calbert1999

    laugh away

  • @joshtrejo Oooopppsss.... just realized these are not SC bypass valves but they are QTP cutouts. Awwww...... I get it now. Was wondering why the sound changed. Either way, I don't see the point on a BMW.

  • @calbert1999 because i wanted both quiet and straight pipe sound on a switch when i would race. here is a pic of my setup below. 250 progressive shot direct port nitrous. sounded way better in person, sounds shitty on video

  • youtube wont let me post link for pictures to it

  • You need to open the garage when pressing gas, it lets off c02 to deadly levels.

  • you wont die from 30sec of fumes lol

  • Hello, It's so good, i'm ready to do the same think, have you got a picture of your electric exhaust system please ?

    Thanks

  • is this stock except for the mid pipe? (im guessing thats where the EVC is)

  • @joshtrejo Yeah. Doesn't sound good at all online. I know the cutouts are expensive so usually done' for additionally unrestricted air flow = more hp's or way cool aggressive sound.

  • @joshtrejo I just don't see the point of doing this on a BMW.

    Look up "Camaro SS .AND. ProCharger race valve" that's the way it's supposed to sound.

  • CO2 won't kill you
