On a 01 sti What is the inside diameter of the 90degress red pipe that connects the turbo ( vf 30 ) to the cast y piece on the under side of the tmic . Also are both ends of this pipe the same diameter ?
The reason for asking is I need a new 90 degrees pipe BUT the side that goes onto the turbo needs to be about 10 mm longer than the standard sti one

Thanks Andy
