Im curious to know who is making a custom pipe specific for a turbo and why the need for a custom pipe ?
Will a custom pipe turn the turbo's fan faster ? And if so how much faster ?
OT
We had a turbo pipe on our OVS Dragon 800, Williamson was building them I believe. Heavier gauge, the different fittings to seal better and different dimensions to make better use of the higher RPM the turbo's like.
