yep. but in reality, you are trying to get the backpressure as low as possible without losing velocity. not try to maintain backpressure. seen it before. a 3" diameter dump pipe connected as the second piece on a 2 piece header on a '00 Si makes 13whp over a full aftermarket exhaust.

What is a dump pipe, was this civic stock, modified motor versus stock= big diference, higher compression = faster exhaust speeds= bigger diameter exhaust

the Si had I/H/E. it was a 2 piece header so he took the exhaust and lower piece of the header off. it was a tri-y header. the header went from 4 to 2 and merged into one 3"pipe that is about 2ft long and dumps it down
