  1. CBV plumback

    Posted by Dylan on 31st Jul 2020

    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.

  2. Noises that make you laugh every time

    Posted by Laithe on 26th Feb 2016

    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
