Drilling out baffles on Yamaha Stryker 1300cc, getting a louder exhaust.

My friend couldn't stand the quietness of his bike's pipes compared to, well, any other bike. So I helped him understand how he could get some volume out of the bike without costing him much at all. The baffle plates on the rear of the bike's exhaust can be simply drilled to allow the raw sound of the motor to be exposed, giving it a partial opening to bypass the effects of the baffles that which is what makes a muffler work...
He thought he wanted 5/8" holes but finally listened to reason, hence the piece of video near the end. In this video I help him to understand aspects in regard to this subject and show him how to get better results other than just drilling random holes.
There are a lot of easy and "free" mods you can do to most any bike or car and this is one of them. I make videos on occasion to help others understand those aspects and save themselves some cash when possible. Check the rest of my videos for other idea on how to save yourself some hassles and cash.

Shame we didn't have a 'before and after' vid.

Thanks for the video, I just (November 5th) finished doing the holes on the exhaust of my Stryker 2015, it sounds great... Thank you very much...

[@cyberjack]

you can just hit the scribe tool with hammer to make a small hole, then drill it.. that's what i did. and if you change your mind later on you scan skew in a bolt into the hole(s) to re seal them

Nice deep rumble

Does this effect the bike's performance? Also, will this have any adverse effects on the motor (burn pistons/ rings, run hot, etc...)?

Just drilling baffles shouldn't affect much..The fuel injection will compensate for the slight difference in backpressure.

john robert thanks for the insight

Same question for a bike with carburetors

[@eric1064]

What size holes did you drill?

Why 3/8 vs 5/8?
