Our jet pipes are double walled and made from the highest standard materials,being light and strong.We deliver each pipe with fixing materials for an easy and fast installation.The standard diametre for this type of pipe is 94 mm at the end.Please check space in your model BEFORE you order !
The lengths in the shop are total lengths of the pipe. As the turbine reaches inside the aluminium inlet of the pipe, the length of your pipe needs to be calculated as follows:
For 15-30N pipes
Measure from turbine exhaust cone to the end of the plane`s nozzle PLUS 20 mm
For 40-80N pipes
Measure from turbine exhaust cone to the end of the plane`s nozzle PLUS 40 mm
For 80-160N pipes
Measure from turbine exhaust cone to the end of the plane`s nozzle PLUS 45 mm
For 160-250N pipes
Measure from turbine exhaust cone to the end of the plane`s nozzle PLUS 45 mm
Example: you have a 60 N turbine and measure a distance of 500 mm from your turbine outlet to the end of the plane, you add 40 mm and will have to order a pipe with a length of 540 mm.
