How-To Remove and Replace the Chain and Sprockets on a 2013 R6 (Most Other Sport bikes, too) 

Hey i have Honda cbr 600cc, What if i remove it’s stock exhaust and do straight piping on it? Someone told me that if you remove it’s original exhaust there will be 90% chances it will badly impact my bike’s engine! And it may explode.

Its 525 120L?

Bro there is an inbus head on the bolt to tighten the chain.
