can anyone tell me the difference in a 4-2-1 and a 4-4-1 header.  i know
that it means for a 4-2-1 that it goes from 4 to 2 to 1 pipe(s) but what are
the performance differences?

I am looking to put headers and a free-flowing exhaust on a '95 civic lx
1.5L 5sp.  if anyone has any suggestions please post.

thanks

A 4 to 1 header will give you better torque (?) at higher rpms

A 4 to 2 to 1 header will give your better mid-range torque.
