Just more convoluted than the earlier ones? Don’t flow as well?

Probably the short primary tube design (like a manifold log design), with a long secondary (each bank) leading directly into a restrictive muffler/egr dump/ + cat. Everything the EPA/CARB needed in a '75-'76 914 to run hot and compliant (IMG:style_emoticons/default/evilgrin.gif)
Nothing in this design bringing performance to the table. |
