can you tell me when you drill at back of pipes to make bike louder how far do you drill in,

hello

1'6"

Sorry, my parents always told me " never talk to strangers"

who are you?

So why you posting to us then?

Get an extra long drill bit

Run it in until you feel this first baffle

Drill a hole of about one quarter inch there

It will be louder and the bike should still run
