The original exhaust has the lower muffler fixed to the rear header pipe via a balance pipe. Is there a particular reason for the existence of the balance pipe? I had wondered if this was essential to maintain the correct back pressure of the exhaust gases?

Do after market exhausts bother with this?

hi awa355

not sure if this helps but have just fitted a set of second hand highway hawk slash cuts these do have the connection pipe

most of the after market pipes i looked at (on ebay) did not have the connecting pipe ?

regards gary

Just the way it's set up.

I never paid too much attention to it and my own custom pipes don't have one.

You can alter the balance at the carb end as well, to reach a set-up that you like.
