Update:
Decided to adjust the tips for a better centering in the cutout.
Initially thought some oxy-acetylene heating would allow me to bend the stainless tail pipes - nope, too tough to bend even at red-hot.
Plan B was then to cut the tailpipes a bit shorter , adjust the polished tips up a bit and apply the oxy to the hangers so I could bend them to get the cans to sit higher.
Better result now. (BBB might approve? )
