If you own a Yamaha and have a factory b-pipe exhaust then you know the struggle.
The two center bolts at the top of the manifold will drive you crazy. Well I got sick of this like you are and made some bolts with 10mm heads
These comes as singles for $5 each, so make sure you order two for both middle bolts
Please make sure you use anti seize or grease when you install these bolts
