Ciruit Racing Exhaust,
#1
Racing a standard 12 A engine RX7 class, does anyone know what the ultimate primary pipe length should be?
I understand the longer the better.
Has anyone running the 2 primarys to their own muffler, i.e no collector box, twin pipe system?
Is there an ulitmate primary pipe diameter?
Remember this is a standard ported engine.
