yea im aware of that2kstreetcivic said:you got a 4-1 Megan 2-piece header right???...thats what it looks like from the pictures...but if that TRUE then you should feel the HP gains in the higher RPMS....a 4-2-1 header gives you gains in the lower-mid ranges and 4-1 gives you mid-high...so thats why you feel it at higher rpms
