I recently straight piped my exhaust. I didnt rejet carbs as I saw no sign of loss of power or any other vital signs. Recently I was reving my engine at night and I noticed when I backfire which happens often since I straight piped I get flames shooting out of my exhaust. I read somewhere that backfireing isnt actually bad for your engine. I guess I just want a second opinion
