any one ever do this' how you make a round pipe fit into an oval hole without distorting. On the passenger side the turn is very tight any help would be appreciated

I grind a steel mandrel to beat into the tube or weld
on a 1"fine threaded bolt so I can take all the tubes
to the local muffler shop... just line up the tubes
at the right angle then mark the top center with a
marker and put a center mark on the mandrel... depends
on how close the first bend is

You can hold the tubes in a vise(rap the tubes with
towels if you have jaws that will hurt the tubes) then
you can heat the tubes and tap the mandrel in easy...
tapping the OD helps shape it while on the mandrel
but dont do much because it tends to open it up more
