"Ekona: Get out there, listen to a few different exhausts on a meet, and pick one"
This. First thing I would've suggested. A lot less hassle than making a leak
Although if you really want a leak that's a lot more technical than making some holes in it I'll give you that
When my exhaust was leaking I did enjoy going into underground car parks I'm not gonna lie lol. But you can't replicate it with a proper exhaust
I see what your saying- do this 'mod' as an experiment to see if you can live with it but I'm pretty sure you've made your mind up that you want one. Take off your flame suit, listen to some local zeds and decide which one you want
If your pockets are deep enough find yourself a veilside exhaust
