Driving with headpipes on manifolds ... ok?

I don't know why not.............

My favorite example is some of the big Rolls/ other aircraft engines. Some of those operated with VERY short stacks......and in very cold temperatures

It’s the weight of the head pipes cantilevered vibrating that concerns me. As for the noise, it’s 15 miles of it. No problem where I live.
