4:55 factory muffler
8:23 driller through factory muffler
Sound like the drilled through one have slightly louder mechanical sound

[@SebSar-ef4zj]

Good demonstration , thank you. I think I'll stick with the stock factory exhaust .Noise and pollution, both at minimum level.

I removed my MT03 exhaust system and replaced it with a full stainless system by Delkevic.Sounds really great,its a joy to ride and hear this exhaust.

[@adventuredownunder2131]

Did you have any fuelling issues afterwards?

[@elricaguilar6693]

Instead of going through the baffle you should’ve use a goose saw big enough to fit around the baffle and remove the whole baffle, that’s why there wasn’t any change on the db measurements

[@gavinmay6949]

It's the one thing about the new Yamaha bikes, majority of the sound reduction is done by the huge integrated catalytic converter. This is why many people just take the muffler off because it literally doesn't do much at all. Just compare a stock ninja 300 pipe to a R3's, the cat is much bigger.

[@pb4633]

remember increase in dB is logarithmic! 3db increase = doubling of "loudness"

[@antehr1]

I`ve tried without top and it`s not so bad, and its easy to test. It`s a little bit better sound also you can drive without him

[@technogentleman3292]

What do you mean with "top"? I will try.

[@adventuredownunder2131]

@@technogentleman3292 I too would like to know the answer

[@33dar36]

if you get rid of that big box in the middle of the exhaust youll have a stright pipe then you can weld the muffler in the end its gonna sound awesome

[@SuperIceman44]

Or you could just get a bend pipe which is dirt cheap :3

[@technogentleman3292]

Did you found another idea after this video to improve the sound level? I'm looking for an idea to be noticed in traffic with a modification on the stock exhaust.

[@IfItAintBrokeStillFixIt]

No I didn't try anything else . The aftermarket exhausts are quite expensive . I wanted something that would be slightly louder but not too " in yer face sound"

[@technogentleman3292]

@@IfItAintBrokeStillFixIt Thats exactly what I search. I meant if you have worked on further modifications but it seems not. Its pity to give lot of money for akrapovic exhaust (non carbon model) which is looking like handmade.

[@brianm5753]

I think the exit exhaust hole needs to be larger. Like removing a db killer

[@bethany-joyrobertson4054]

On a side note just noticed you have a top box I can’t find a bracket anywhere for one which did you use?

[@IfItAintBrokeStillFixIt]

I ordered it with the bike. You might have to go to Yamaha

[@michaelgunderson7415]

You need to get rid of the cat if you want it to get louder.

[@kaneellison1160]

Do r3 after market exhaust fit on a mto3

[@adventuredownunder2131]

Yes

[@chrisj5110]

What hand guards are you running?

[@IfItAintBrokeStillFixIt]

Chris Janzen . check my other clips , i have made a clip on fitting them. Thanks

[@chrisj5110]

Found the clip. They look good. You happy with their performance?

[@IfItAintBrokeStillFixIt]

yes I think they look good on the bike, I bought them originally for winter use thinking they would stop the wind chill , had very little effect thou . Thanks

[@Voltomess]

Thank you Sir looks like it's not worth it.
