Fix and reconnect kitchen extractor hood ducting

Hi, I need someone to fix the ducting connection of my kitchen extractor hood. Current situation: The extractor is venting into a horizontal 110mm pipe near the ceiling. The current flexible connection has a tight U-bend and poorly sealed taped joints, causing air and cooking smells to leak inside the house. What needs to be done: Remove the current crushed flexible pipe and old tape. Fit a proper, direct connection from the hood outlet to the pipe/elbow (ideally using a straight/semi-rigid duct or proper elbow to eliminate the bend). Securely clamp and seal all joints with foil duct tape to make it 100% airtight. Please check the attached photos for full access and current setup.
