iriz

ok.ive just changed my muffler from straight flow to s-flow.
yeah i know,its sucks because i cant go rempit anymore.hahaha.

ok heres the problem.the powwer output seems low/reduced.
so i want to balance back the power output as like i'm using straight flow muffler.

my currrent setup is 2.3inch piping(the old straight flow muffler).
so do i have to change the piping to a bigger size than the 2.3 inch piping?
as to balance out the back pressure as ive installed the s-flow muffler...
