i read in faq that you cant really feel the difference between a 4-2-1 and a 4-1 manifold? [/quote
you cant tell the difference betwen them really until you start to really fine tune your engine with cam timing and adjustments on the rolling road. I had to fit my standard manifold back on recently and couldnt tell the difference at all from the janspeed one.
