Hey Bud,
Many have done with double wall pipe.
It weigth less and run cooler.

Can I replace the old BVM single wall stainless steel tailpipe ,ceramic blanket, aluminum foil ,sheet .003"aluminum outer tunnel and ejector nozzle with just a dual wall tailpipe?
Seems to me I could save a bit of weight in the aft end.
What are you guys running?
