Haha...from the beginning i know there is some risk to do tht..but no matter how must try also ma..rite? N thankz god..the cover managed to fit in..extra 1mm also cant fix in..coz side of the flare is touching the side wall or the cover(1st trumpet). But surprisingly..after taruh back cover..can feel power better than without cover..pycological or wat?*blur*
They tried to put the blame on my tuning but did not even bother...
