i think if its the right size piping u shouldnt lose power anywhere...
??? is that a fair assumption?!
i had a 2.5" full system in my b18c... and when i went back to stock system, i noticed a loss in response and topend. i thought i would atleast notice a more responsive low-mid range zippy feeling. but alas i didnt.
so get the right size piping for your application and it should be fine.
normal jap stuff for our hondas always soom to be round 60mm. so thats a good place to start! good luck!
first mod to do to your honda is extractors with 2.5" collector and cat back (piping diameter 60.5mm) and free flowing muffler - if you have only invested in a b pipe
and yes bummdyno shows that this will yield greater driveability and more freely flowing revs.
