My DIY 3" exhaust system
Hi decide to make my own 3" exhaust system for my ZD30 patrol so i got another dump pipe off of SHREK to use as a template, i then made a turbo flange out of 12mm plate with a 50mm hole in it to suit the turbo outlet the machined it out to 70mm x 6mm to suit the 70mm pipe I'm using as the 3" would fowl on the stud bolt nuts
i then cut a 70mm or 2 3/4 90 degree bend down so it would closely match the standard
I later had to cut the 3" adapter off as it was not long enough to which i made my own my cutting slices down a piece of 3" pipe then clamping them together to make a a opening of 2 3/4
Then i fitted it all up tacked it then checked it before finally welding it
now thats done I'm going to buy a Beaudesert Exhaust tail pipe section in 2 3/4 for a little more clearance around the back then next is to make the rest from the dump back to the tail pipe using a muffler and a flex joint.
more photos to come
