This pipe is thick walled and is rigid enough to prevent walls from collapsing under load **.  It is custom designed for those wanting to install a high flow turbo with different intake sizes in conjunction with the factory turbo airbox (has a 70mm downwards facing outlet).

** if your snorkel is too restrictive with a high flow turbo the pipe can still pull in and will need extra clamps to support but ideally an upgraded turbo.
