Dennis,
The older style 4-1,all the head pipes meet at the
same point, 4 into the 1 collector.
With the 4-2-1,the 2 front head pipes meet at a 2-1
Y,along with the 2 rear head pipes,this 2-1 then goes
into the 1 pipe back to the can.
I don't know if this answers your question,as for
performance,I dont know what the difference is,if
any,maybe more mid-range? I dont know.
