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. (IMG:style_emoticons/default/agree.gif) The early 2.0 HE's are not headers but at least they're two pipes that go straight back. Headers are the only true bolt on HP, although the increase isn't that big on a stock engine, on performance engine the difference using a good header is huge. |
