    Z20LEH Jet noise ?

    Hello !

    Watch this video and listen to the engine jet noise on this VXR.
    http://www.youtube.com/watch?v=LfNXHh25G4E

    Where that jet noise come from ? My Astra VXR/OPC does not make that sound even being the same car (Z20LEH) !! I like it !!

    Do you guys know what I must check to make my car sounding like the one in the video ?

    Thanks !!!

    I'm sure I read when they VXR was first released that the exhaust was "tuned to sound like a jet engine" ...

    Standard ZLET's don't sound like it, but hearing spanish's phase 3 coupe they most certainly can do!

    Mind due he's running 22psi.

    I personally love the sound. reminds me of nissan pulsars.

    I get that off mine and I'm damn sure it spat out a flame yesterday - normally it spits and splutters but it was a right bang yesterday as I let off after caining it in 4th!!

    I'm running 20 ish psi with no cats and 2.5 straight through
