604 header question

[dogface]

What length pipes if any need to be added to headers on 604. we are running beyea

[brad hibbard]

the extensions and mufflers that come with the beya "crate" headers need to be used for proper performance

the power curve can be tweaked a bit in different diretions with different length pipes and there are different nuffler designs available that can also make specific benefits but a well rounded base line is the way they are sold from beya

everytime I hear a guy say that they were not at all satisfied with beya headers---I ask them which muffler they are using and everytime they have responded with----we don't have to run mufflers---------------------

the muffler and pipe extension is part of the package----it will not work correctly without it
