The exit modification does little for Hp...at least on a chassis dyno.
I have opened them up from the 1 7/8" to 2 1/8" then finally as much as 2.45" and only found that they hold peak Hp for 200 additional rpms before falling off.. I even cut the crushed neck off the pypes head pipe, and made my own entrances.
I'm still not done though...This year should be a record year for the "Log". Jeremy and I will make lemonade out of these lemons yet!
