sparks exhaust and 13tooth sproket

[MAD450r]

Anyone here running sparks full system and still think it needs a 13 tooth front sproket?

The reason I ask is I should recieve my exhaust thursday and wonder if I still should pickup a crf sproket, or should I wait?

i put the sparks system on this weekend and i have decided that i don't need the smaller sprocket, but everyone has there own opinion.
