Hi OCA1, Many thanks for your great comment
Regarding IDP Tuned Pipe, This one was made by my enthusiast friend as a limited edition for the circuit driving use.
The design is based on 30 products in the 80's.
The outside diameter is following to the early production of DELTA,Which was a really rare item with narrow shape.
The method of welding is completely the same as the vintage style.
The exhaust sound is shrill and the power is much enough.
This one is not used only circuit use but also the restoration of the vintage.
It's a such lovely pipe:D
