Louder without retuning

[Revcogg]

How can I make the pipe louder without having to have my bike reprogrammed? I am running 12 disks with a closed end cap. Can I use the open end cap and fewer discs? And will that make it louder? I recently removed the end cap completely and really liked the way my bike sounded but don't want to ruin the engine running too lean. Thanks

The open end cap will provide more sound and your exhaust flow can remain the same for tuning purposes.
When swapping to an open end cap;
3" discs, remove 6-7
4" discs, remove 10-12

Thanks for the help!
