Thread: SR16VE exhaust ports

venturi's principle

Not venturi, that would be smooth, the step is to prevent reversion pulses, a venturi would not stop those

I just received a generic ceramic 2.5 inch header from e-bay too, and noticed that te primaries appear to be larger than my older 2 inch SS header. However, the flange looks like it is the same size. I'll have to check it against the head to see if the ports line up, but if they don't, there is room to grind part of the flange.

I'll be doing this install this spring, so to save the header from at least one Canadian salty winter, but I'll keep you informed.
