B18 Header

What is the best header for a n/a B18c1 with spray? Would you go with a 4to1 or a 4to2to1?

Thanks,
Chicago Mike

Re: B18 Header (SI HB 90)

the 4-1 will help out the top end, and the 4-2-1 will help out the midrange power

i would say go for the 4-2-1 since these engines have no torque, and that can hurt the midrange power....

The B18 have a bunch of torque compaired to the B16 I was kinda thinking 4 to 1It is in an EG so its not a heavy car.
