    Turbo smart compressor bypass valve

    This is a great quality product to replace the old oem. This product does however need to be professionally installed. On the LS/LT XR5.

    Easy install

    Very easy to install from the drivers side, take wheel off, use extension with Allen key. The quality over stock circ valve is out of this world...

    Turbosmart parts are always a please to fit. However gaining access to the location of these on the XR5's is quite the task.

    Louder than expected

    Genuinely surprised with how good this sounds considering its the legal version. Was expecting something simple but it's a beautiful flutter with several tones to it. 10/10

    CBV plumback

    I am really impressed with the throttle response it gives and really happy with how quickly I got it from QLD, It only took 25 min to install with the right tools and with an open air intake you'll hear a flutter 5 star from me.

    Noises that make you laugh every time

    After researching and finding the CBV is a weak point in the 5 pot design I upgraded, and when combined with an aftermarket intake with a pod filter the sound is amazing and will keep you entertained with flutter noises
