exhaust
Part of my plan includes omitting the stock exhaust and going with something a little lighter and a bit more loud.
How *BAD/Inefficient* are the 75-76 914 stub pipes? b

Louder? What did you say? Engines do need some backpressure through the exhaust to achieve the right breathing characteristics- exhaust pulses help evacuate the cylinder. I'm guessing that just stub pipes would not be an improvement, it would take a more complete design effort to get the right manifold/ cam/ stub lengths/ timing advance combo.
