6" SS EXHAUST STACK

[Gregory OConnor]

Kurt, try and figure why there were 4 bends. it may be that it was
engineered to alow for swing room between the 'hung exhaust' and
the 'torque reaction of the ruber mounted detroit'. look at the roll
of the torque and see that there is a place for the movement to twist
a union. I kinda think this movement was the problem with the
resulting crack. crack=result ;movement=cause ;facilitate movement
=repair. may be that BB enginered it correct but someone
overtightened a band to cure an exhaust leak??????? you also got to
keep the stack from cantilivering off of the maniford with your new
design. Scavenging is one variable in fuel efficiency. even straight
pipes some time will result in lower fuel economy because the intake
variable get screwd. backpressure is mathed into the computer.
