The long-tube headers improved the power output through the entire rev range, a clear illustration of the scavenging effect offered by the design.
Do you need test pipes with long tube headers?
Long tube headers will replace our crappier stock headers and cats. Essentially like short tube headers + test pipes, but with a longer length before the tubes merge. This should give the biggest gain (best exhaust flow) and most likely save the most weight, but install is the most complicated.
