Hi guys,
Not sure if anyone here would be interested, but there is quite a lack of info for the QPV.
There isnt much that can be improved from a performance side on the intake of the QPV, its pretty perfect.
Noise wise however..:
There are two resonators on the intake duct, turns out these reduce quite a bit of noise when on full throttle from 3k upwards. Removing them has released a wonderful noise.
The modification is completely reversible, and is only evident on full throttle from my experience.

Parts required:
Revotec 10mm adapter.
10mm female coupler.
10mm ID Jubilee Clamps
Ash 4" to 3.5" reducer
4" and 3.5" ID Jubilee Clamps 20180526_095641.jpg

The Reducer needs shortening by 15mm. But the rest is very straightforward:

And side by side for comparison:

That certainly does look like a tidy job. I have to admit that a little more intake noise would be a good thing.

Hey,
Mine only had the one 10mm take off. Is yours a duoselect? In which case it may have another takeoff, just add another 10mm fitting.
I can try and get an after vid but too late for a before vid now! :)
