Today guys oxygen wielded the modified parts this morning then attempted the install. Whilst fitting some o rings were changed over. One bracket was connected to the end cap fittings below the rear end of the exhaust to ensure to loose ends and vibrations. Also had to take out the old heat exchanger used many moons ago whilst running SVO near the right corner marked in green. In doing this freed up space and accessed the A/c pipe and made life easier to remove, weld a T bend and reattached whilst trying to make it look OEM.
