round vs square exaust?

  1. I am currently building a custom reverse flow, cc is 36" x 24" x 24" , fb is 24" x 18" x 18" , question is 4" x 30 in stack or should I go square? If I go square what diameter and length? Help and info is appreciated. Thanks

    Add to the "diameter" of the square if you use it.... The additional surface area will cause additional friction...
