Hi all sifus here ~ i just changed the myvi stock exhaust to cat back from Supercircuit ~ just wondering, is such change increases the fuel consumption ? lots ? any ideas ? but, yeah, i realize it might be hurting, just wondering how significant it is going to be.
im still trying my first full tank ron 97 (pump stopped automatically), just wanna prepare myself mentally, if worsens, might consider sell it though ~
