6" SS EXHAUST STACK

[Pete Masterson]

Having recently replaced my muffler (at great expense) -- had I to do
it over again, I'd have switched over to a 5" system from turbo to
stack. As others have stated, it's 5" at the turbo outlet and the
standard in the heavy truck industry is 5".

The only performance difference I notice (between the old blown out
muffler and the new one) is that the exhaust-type Jake brake seems to
be slightly less effective.
